  • Patent number: 6568654
    Abstract: A mechanism used for locking a valve that provides positive control of the valve lock to prevent the valve from changing position unintentionally. The positive locking valve control device preferably comprises a push-pull rod having a toothed configuration that is engaged at different positions by a spring mechanism on the valve locking device in order to hold the push-pull rod and thereby the valve securely in place. To adjust the opening of the valve, the push-pull rod can be rotated by some predefined amount (such as 90 degrees) clockwise or counter-clockwise. This rotation frees the locking spring on the valve locking device from the teeth aligning it with a side of the push-pull rod thereby permitting linear movement of the rod to cause a corresponding adjustment in valve position. The rod is then “pushed in” or “pulled out” to adjust the size of the valve opening until the desired flow through the valve is obtained.

    Abstract: A cutting torch allows the preheat oxygen and fuel valves to remain in a preset position while the torch is off. The cutting torch has preheat oxygen and fuel cutoff valves mounted in line with the adjusting valves. The cutoff valves are both operated linearly, each having an axially moving plunger. An actuator simultaneously moves the cutoff valves between opened and closed positions. The actuator has a locking device to lock them in the opened and closed positions. A pilot flame igniter utilizes a piezoelectric crystal and a pilot fuel valve positioned side by side with parallel axes. An igniter actuator in a single stroke opens the pilot fuel valve and causes an electrical spark to ignite the pilot flame.

  • Patent number: 5286000
    Abstract: There is disclosed a wand activated dispensing valve that can be installed on the spouts of water faucets. The valve includes a housing having an internal cup-shaped member with the bottom wall of the cup-shaped member being foraminous and having a substantial thickness. The bottom wall preferably has a plurality of circumferentially disposed radial slots in an outer annular area, surrounding a central wand aperture which receives a rod-like wand. Preferably the wand aperture is surrounded by an internal recess in the bottom wall of the cup-shaped member which receives the bulbous upper end of the wand, capturing the wand in the assembly. The lower end of the valve member rides on the bulbous upper end of the wand and the valve member is lifted when the wand is tilted to one side. The housing includes a valve plate having a central port which receives the valve member, the upper end of which seats against a valve seat carried by the valve plate.

  • Patent number: 5259588
    Abstract: A drain valve includes a valve body, inlet and outlet ports, a first bore communicating between the inlet and outlet ports and a second bore intersecting the first bore at a right angle. A slidable member is mounted for reciprocal movement within the second bore. The slidable member includes a pin comprised of a resilient composite material, such as virgin tetrafluoroethylene, which maintains its resiliency throughout a wide range of temperatures and pressures. The diameter of the pin is slightly greater than the diameter of the second bore. As such, the pin is compressible to allow the pin to be inserted into the second bore and is expandable against inner surfaces of the valve body defining the first and second bores to provide a positive seal along substantially the entire length of the pin. An effective seal is maintained, despite variations in temperatures and pressures, to prevent leakage and accidental movement of the slidable member. A slot is cut in the pin to function as a guide slot.

  • Patent number: 5203688
    Abstract: A fuel gas control valve capable of internationally acceptable operation, including a main valve operable in an on-off mode by an electromagnetic actuator that receives a signal from a conventional electric thermostat. A pilot valve is initially operated by a manual control, and is retained in the operating position by a power unit responsive to sensed presence of a pilot flame. A latching mechanism associated with the manual control interrelates with the main valve and overrides operation of the electromagnetic actuator in the event the pilot flame is extinguished for any reason. The valve also includes a mechanism that retains the manual control in pilot position until the pilot flame is established.

  • Patent number: 5123369
    Abstract: A valve apparatus for a marine vessel has a housing with first, second, and third ports and a valve member within the housing. The housing is mounted to the hull of the vessel with the first port communicating with the body of water outside of the vessel. The third port is connected to the cooling system of an engine in the vessel and the second port is closed by a quick-release plug. The valve member is movable to open and close communication with the outside. During normal operation, water is drawn through the structure into the engine cooling system and is discharged overboard. In an emergency, the plug can be removed and the valve member moved to a 90.degree. position in which communication with the outside is closed, allowing the engine to draw water from within the hull and discharge it overboard. The structure can also be used with a service adapter for engine flushing and other maintenance.

  • Patent number: 4948092
    Abstract: A combined check valve and relief valve assembly for permitting the free of a fluid in a first direction and for selectively preventing backflow. Backflow occurs only upon depression of a compression spring-loaded cylindrical valve actuator housed within the valve body. The valve assembly comprises a valve body having an inlet and outlet port which are adjacent to an upper and lower cylindrical bore respectively, thus providing a flow path. A resilient duckbill valve is mounted within the cylindrical bores. A compression spring-loaded valve actuator is also received, lossely, within the valve body and is provided with a stem at the end of the valve actuator, proximate to the opening of the duckbill valve. Fluid passing through the upper cylindrical core around the valve actuator opens the lips of the duckbill valve permitting free passage therethrough. Back pressure seals the lips of the duckbill valve so that the valve becomes a check valve.

  • Patent number: 4944484
    Abstract: A gate valve is provided which includes a body having exterior catches and a handle with resilient latches integrally formed with the valve stem to snap lock over the catches on the body when the valve is closed. The gate valve closes and locks simultaneously to cut off flow through a passage by a single axial motion and is unlocked to open the valve by rotational motion. Further, when the resilient latches snap over the catches, the operator hears an audible snap thereby assuring the operator that the valve is securely locked in the closed position. The gate valve body is preferably formed by ultrasonic welding of two identical half members.

  • Patent number: 4844415
    Abstract: A valve, which is especially suited for use in connection with a urine bag, has a cylindrical valve body, which is displaceably and rotatably mounted in a tubular valve housing having a transverse flow passage defined therein. A projection formed at one end of the valve body may be brought into engagement with a cut-out or notch in the adjacent end of the valve housing. In this position in which the projection engages with the notch, the valve is open, because the transverse bore of the valve body is aligned with the flow passage. The valve may be closed by displacing the valve body in relation to the valve housing so as to bring the projection out of engagement with the notch, and the valve body may be rotated in relation to the valve housing, if desired. The engagement between the projection and the notch ensures that the transverse bore of the valve body extends coaxially with the flow passage in the open position of the valve.
