  • Publication number: 20110048423
    Abstract: Low pressure oxygen or other breathable gas is supplied from a tank or other source to a patient or other person through a flexible plastic tube, and a safety valve system is connected between the source and the tube. The valve system includes a valve member having a tubular outlet portion and supported for axial movement within a valve body having an inlet connected to the gas source. Fluid passages are formed within the valve member and valve body, and the valve member shifts axially to an open position in response to connecting the flexible tube to the tubular outlet portion of the valve member. The valve member shifts to a closed position in response to removing the tube from the tubular outlet portion, and the supply gas holds the valve member in the closed position.

  • Patent number: 7891372
    Abstract: The present invention is directed toward an anti-contamination arrangement for a valve having a valve housing, a bushing positioned in the valve housing, a valve member including a valve shaft and a valving portion operable for engaging a valve seat, slidably disposed through the bushing, and a supply port operably associated with the valve member. The valve also includes a control chamber controlled by the valving portion, and a valve seat positioned between the supply port and the control chamber. The valve member is operably associated with the valve seat for controlling the flow of fluid from the supply port to the control chamber upon the movement of the valve member in relation to the valve seat. There is also an anti-contamination arrangement positioned between the bushing and the valve shaft for collecting and removing contamination from the valve member.

  • Patent number: 7886942
    Abstract: A valve for a liquid dispensing system includes a casing having an interior sidewall. A hollow dispensing pin is positioned within the casing. The dispensing pin has a first end, a second end, an exterior surface, and an interior flow passage. At least one radial dispensing passage extends from the interior flow passage through to the exterior surface at the first end of the dispensing pin. A first plunger is disposed between the interior sidewall of the casing and the exterior surface of the dispensing pin. The first plunger engages both the interior surface of the casing and the exterior surface of the dispensing pin. The first plunger is movable between a closed position blocking any flow through the at least one radial dispensing passage and an open position toward the second end of the dispensing pin spaced from the at least one radial dispensing passage.

  • Patent number: 7849876
    Abstract: A valve assembly (10) comprising a valve member (14) having surfaces (70, 72, 74, 76, 78) radially sized and axially situated to provide an axial sealing force to insure leakfree operation. When the valve member (14) is in a supply position, the sum of fluid forces imposed on the radial surfaces is positive towards supply position, and, when the valve member (14) is a nonsupply position, the sum of fluid forces imposed on the radial surfaces is positive towards the nonsupply position. The valve assembly (10) is compatible with a piezo-type actuator (18) that provides lift-shift forces early in its stroke. Once movement of the valve member (14) has been initiated by the actuator (18), the fluid forces can be relied upon to complete the shift and seal the valve member (14) against the corresponding seat (40/42).

  • Publication number: 20100263733
    Abstract: A dental syringe may include a replaceable valve cartridge containing one or more valves which may use a seating surface and an opposing seating surface with a relative angle formed between the two surfaces. The relative angle allows for regulation of the flow of fluid. The replaceable valve cartridge may also include a system to remove a residual liquid from a tip of a dental syringe. Additionally, the replaceable valve cartridge may include a seal that prevents bleed-over of fluids. Further, the dental syringe may comprise a tip retention insert which may use either a pair of plates or a plurality of ball bearings to retain the dental syringe tips. An alternate embodiment of a valve may comprise features intended to reduce the force necessary to actuate the valve. A metering screw and/or flow-control groove with increasing depth may control of flow through the valve.

  • Publication number: 20100212076
    Abstract: A valve mechanism for controlling release of pressurized fluid includes a fluid chamber. A plunger is received in an aperture in the fluid chamber, and is movable between a fluid retention position in which fluid is substantially trapped in the fluid chamber and a fluid release position in which fluid can escape from the fluid chamber through passages in the plunger. The plunger is biased into the fluid retention position. A driver drives a plunger actuator, and the plunger actuator is guided into engagement with the plunger to cause the plunger and the plunger actuator to move in unison and move the plunger into the fluid release position during a first portion of a stroke of the driver towards the fluid chamber, and the plunger actuator is further guided to permit the plunger to return to the fluid retention position during a second portion of the stroke.

  • Publication number: 20100181519
    Abstract: An automatic valve includes a three-way valve body and a valve core disposed in the valve body. The valve core has a large flange and a small flange formed at middle and front sections, an axial hole therein, and a water outlet formed between the large and small flanges. The water outlet interconnects with the axial hole. The valve body has a front section connected with a connector. A retaining head is inserted into the connector to connect with the valve core. The small flange of the valve core is moved to seal the connector. The water flows into the axial hole, out from the water outlet of the valve core, and into the chambers of the valve body. The valve body may use one side port to connect with a feed pipe and the other side port and the lower port as outlets to connect with outlet devices.

  • Publication number: 20100090150
    Abstract: A valve assembly comprises male and female coupling members that are connectable by inserting a probe of the male member into a socket of the female member. A fluid passageway within the female member has an aperture within the socket that is open and closed by a first closing member that moves within the socket. A fluid passageway within the male member has an aperture on the probe that is open and closed by a second closing member. When mated fluid flows between the two fluid passageways. The female member includes a first cage. During insertion of the probe into the socket, the first cage releasably locks the first closing member to the probe such that the cage carries any separation forces created due to the pressure of the fluid within the passageways.

  • Patent number: 7677268
    Abstract: A fluid distribution system for controlling the operation of a swimming pool cleaning device includes a housing having an inlet for receiving a supply of pressurized fluid, a plurality of outlet openings and a valve chamber between the inlet and outlet openings. The housing has at least one compound cylinder having two portions with different bore diameters for slideably accommodating therein a mating stepped piston. Each portion of the compound cylinder fluidly communicates with pressurized water in the valve chamber via associated fluid pathways. The larger cylinder is vented by a relief valve actuated by a fluid driven cam that periodically opens and closes the relief valve. When the relief valve is closed, the pressure within the large cylinder pushes the piston to a first position which effects the opened/closed status of a port, e.g., allowing one of the outlets to communicate with the pressurized water in the valve chamber.
