Abstract: A fill station permits transferring a gas, such as a compressed gas from a second device to a first device. The fill station includes a body having an inlet, an inlet/outlet port and an outlet. The body has a passage extending between the inlet, the inlet/outlet port and the outlet. The passage includes a central passage portion. The body includes a bore therein in communication with the central passage portion. A valve assembly includes a seal, a seat, a ball and a biasing member mounted in the body at a first side of the central passage in communication with the inlet/outlet port and a seal, a seal support, and an actuator shaft positioned in the body on an opposite side of the central passage portion. Engagement of the actuator shaft with the ball moves the ball off of the seat to open flow communication from the inlet/outlet port to the outlet and disengagement of the actuator shaft from the ball moves the ball onto the seat to close flow communication from the inlet to the outlet.

Abstract: A transurethral catheter kit containing a balloon catheter and a syringe assembly adapted for inflation of the balloon. The syringe assembly includes a syringe and a nozzle incorporating a narrow bore proximal to a pressure relief valve. The narrow bore serves to resist the flow of fluid between the syringe and the balloon, thereby avoiding a rapid pressure increase in the balloon that can result in damage to tissues or premature activation of the pressure relief valve. Also provided is a method for correctly placing a transurethral balloon catheter in a patient using the kit.

Abstract: A valve for regulating the flow of fluid through an access port in a fluid chamber includes a body having a first end and a second end, the second end being located in the access port and the first end protruding outside of the access port. An axial bore extends from the first end to the second end, an injection fitting is formed at the first end of the body in fluid communication with the axial bore, and the second end of the body includes a selective sealing interface. The body forms a sealing interface with a threaded inner wall surface of the access port. A one-way valve assembly is positioned within the axial bore, and is arranged to permit a flow of fluid therethrough in a downstream direction and prevent the flow of fluid therethrough in an upstream direction. A bypass passageway extends from the selective sealing interface separate from the axial bore. A connecting passageway connects the bypass passageway with the axial bore upstream of the one-way valve assembly.

Abstract: The outlet switch device includes a fixed unit, an outlet switch mechanism, an inlet switch mechanism and a driving mechanism. The outlet function switch is realized through the relative rotation between the outlet switch mechanism and the fixed unit; the fixed unit includes a control cavity and an inlet waterway connected to the external water resource; the outlet switch mechanism includes a switch plate, which is movable connected inside the control cavity and divides the control cavity into an upper cavity and a lower cavity; the inlet switch mechanism controls the inlet waterway to control the water turning into the upper cavity or the lower cavity, making the switch plate move up and down with the effect of the water; the driving mechanism is disposed between the switch plate and the fixed unit to transform the action up and down to rotation.

Abstract: An apparatus for equalizing pressure in a middle ear includes a hand-held air source for providing a continuous flow of air at a predetermined rate and a tapered sealing nostril plug adapted to be sealed against a nostril. The tapered nostril plug has a channel there through for delivering the continuous flow of air. The channel of the tapered plug is adapted to be placed in communication with the air source through an adjustable valve assembly for selecting a pressure limit for the air in the channel of the nostril plug.

Abstract: A method and apparatus for reducing operating costs and emissions in a pumping installation. A first step involves providing a flow dividing apparatus capable of dividing flow from a pump. The apparatus has a single inlet and two or more outlets. A second step involves coupling the flow dividing apparatus with a pump of the pumping installation and directing flow from the pump through the single inlet of the flow dividing apparatus. The pump will generate a flow stream from each of the two or more outlets and perform work that, in the absence of the flow dividing apparatus, would have to be performed by two or more pumps. The reduction in the number of pumps used necessarily reduces both operating costs and emissions.

Abstract: In a series progressive divider valve having a number of identical valve units disposed adjacent to each other, each formed by a base member and a spool member having a movable spool therein, a manifold in the form of a plate which can be inserted between the base member and the spool member of a valve unit which modifies the flow of lubricant in the event one of the output ports becomes blocked or restricted. In the event such a blockage or restriction occurs, a relief valve disposed in the manifold plate is opened which establishes communication between two normally non-communicating bores which results in the re-routing of the lubricant to the succeeding valve unit. The manifold permits the overall output/lubricant delivery configuration of the divider valve to be continued in the event of such a blockage or restriction.

Abstract: According to the present invention, water regulation assemblies disposed in the water supply path of conventional fixtures are modified to include a pressure relief assembly which permits release of water under elevated pressures. A shut-off seal of a fixture is by-passed by a pressure relief water path which opens in response to elevated pressures. This permits relief of elevated pressure in water supply lines which might otherwise produce a burst event within the water supply lines. The path includes a stopper having a compressed channel that opens to release water at the elevated pressure.

Abstract: A fluid flow control valve, e.g. a pressure vacuum breaker, includes a thermal expansion relief valve for protecting the control valve against damage due to freezing. The control valve has a valve body of rigid material and defines a main conduit. The thermal expansion relief valve has a relief valve body mounted to the main valve and defines a relief conduit in fluid communication with the main conduit, a valve element the moves within the relief conduit between a first sealing position in engagement with a valve seat to resist flow and a second position spaced from the valve seat to allow flow from the main conduit through the relief conduit, and a spring urging the valve element toward sealing position with a predetermined force selected to exceed normal operating pressure of the main valve and to lie below pressure damaging to the main valve. A thermal expansion valve for protecting fluid flow control valves, e.g. by retrofit, is also described.

Abstract: An electrically operated valve assembly having a plastic body with a solenoid coil attached for moving an armature valve member for effecting flow from the vale inlet to outlet. In one embodiment the armature is a pilot valve slidably movable in a guide over which the solenoid is received. A spring loaded check valve in the guide releases over pressure within the valving chamber. In another embodiment a spring loaded check valve in the body inlet passage releases over pressure to a bypass passage to the outlet. In a third embodiment a slug having a spring loaded poppet relief valve is welded over an opening in the inlet passage at generally right angles to the inlet fitting to provide direct relief of over pressure in the inlet.

Abstract: An improved valve for use in angioplasty comprising a cup shaped body having a piston adapted to slide into a first and second position therein. A passage and a plurality of chambers and openings are formed within the piston. The piston is biased in a first position to align openings and a passage for fluid to flow through a chamber and a one-way valve to inflate a balloon catheter. When the piston is forced into a second position, openings are aligned to permit fluid to flow from the balloon catheter into a chamber through a second one-way valve to rapidly deflat the balloon catheter. A balloon catheter can thereby be quickly deflated easily by a physician.

Abstract: A high pressure hydraulic flow control valve is formed with a spool which is capable of operating as a conventional spool to control the flow of fluid from an input port to an output port or to a return port. The spool also provides overload protection which will permit fluid to pass from the input port directly to the return port when an overload pressure condition exists in the fluid supply line. In alternative structure, the overload pressure release system may be incorporated into the valve which is used to control the return of fluid from the output port to the return passage. The high pressure hydraulic flow control valve is formed from a die-cast housing and has hardened seats mounted in access passages so as to bear against a seating shoulder. Preferably, a retaining sleeve is mounted in the access passage to bear against the hardened seat to retain it against the seating shoulder.

Abstract: First and second outlet ports are connected to an inlet port. A first valve member selectively blocks and unblocks the first outlet port. A second valve member selectively blocks and unblocks the second outlet port. A first device urges the first valve member. A second device urges the second valve member. A movable member disposed between the first and second valve members allows a force of the first urging device to travel to the second valve member. The movable member can be driven by a solenoid winding. When the solenoid winding is deenergized, the first valve member is moved to its open position by the first urging device and the second valve member is moved against a force of the second urging device to its open position by the first urging device. When the solenoid winding is energized, the first valve member is moved against the force of the first urging device to its closed position by the movable member and the second valve member is moved to its closed position by the second urging device.

Abstract: A modular color changer provides selected paint colors for spraying and continuously recirculates both selected and non-selected colors. A module is provided for each color to be selected and includes supply and return manifold blocks defining, respectively, portions of a respective universal supply manifold and of respective universal return manifold. Port control valves are utilized to control paint flow therethrough, under normal supply pressures. Solvent and air purge valves are used for cleaning. The changer is particularly advantageous when used in high pressure spraying systems. Modules can easily be added to a basic changer to increase the number of selectable paints.

Abstract: A check valve incorporating inspection valve means therein for disclosing the presence or absence of fluid on the "upstream" side of the valve.

Abstract: The disclosure is directed to a diverter coupling, for use in connection with a water-powered appliance, for coupling the appliance to a water outlet, typically a standard household faucet. The diverter coupling is constructed predominantly of molded plastic parts, to accommodate low cost manufacture, and includes detachable sections mounted respectively on the faucet outlet and on the end of the inlet tubing to the appliance. When the two parts are coupled together, water flow from the faucet is diverted into the appliance inlet, flows through the appliance, and is returned and discharged at the sink. Pressure regulating means prevents overloading of the appliance by excessive water pressure.
