摘要： An air turbine starter (100) is provided that includes a check valve assembly (173). The check valve assembly (173) comprises a valve body (181), a valve seat (179) and a valve element (177). The valve body (181) includes an inlet port, an outlet port, and a flow passage (182) extending therebetween. The valve seat (179) is coupled to the valve body (181), extends at least partially into the flow passage (182) and has an opening therethrough. The valve element (177) is disposed within the flow passage (182) between the valve seat (179) and the valve body outlet port. The valve element (177) is also configured to translate axially between an open position and a closed position in response to a pressure differential between the inlet and outlet ports.

摘要： A flow limit valve for limiting the flow rate of a pressurized fluid includes a valve body with an interconnecting cavity of circular cross-section. Within the cavity is a piston (31) that slides within the cavity under force generated by a pressure differential across the piston (31) to a closed position in engagement with a seat (29) at the end of the cavity. A first encapsulated magnet (45) is carried within the valve body in a chamber located on the side of the seat (29) opposite the cavity. The first encapsulated magnet (45) can be moved in response to another magnet (75) outside the valve body to move a pin (110) which can extend through the seat (29) when the piston (31) is in a closed position to thereby move the piston (31) to an open position. The magnetic forces applied through the valve body affect internal valve operation via the pin (110) and thus avoid the danger of noxious fluids escaping through sliding seals or flexible membranes.

摘要： Embodiments described herein provide a valve construction. One embodiment comprises a first valve (12) and a second valve (14). A first fluid conveying conduit (16) fluidly conveying a first fluid is fluidly connected with the first valve (12). A second fluid conveying conduit (18) fluidly conveying a second fluid is fluidly connected with the second valve. A third fluid conveying conduit (22) is fluidly connected with the first valve (12) and the second valve (14). The first valve (12) is movable between a first position where first fluid flows between the first fluid conveying conduit and the third fluid conveying conduit, and a second position where first fluid does not flow between the first fluid conveying conduit and the third fluid conveying conduit. The second valve (14) is movable between a first position where the second fluid flows between the second fluid conveying conduit and the third fluid conveying conduit, and a second position where the second fluid does not flow between the second fluid conveying conduit and the third fluid conveying conduit.

摘要： A flow limit valve for limiting the flow rate of a pressurized fluid includes a valve body (9) with an interconnecting cavity (23) of circular cross section. Within the cavity is a piston (21) that slides within the cavity under force generated by a pressure differential across the piston to a closed position which prevents fluid flow through the valve. A pin (49) is provided that is attached to the piston (31) and that protrudes through the piston seat (29) into the outlet side of the cavity when the piston is at the closed position. Opposite the pin (49) is an encapsulated magnet (45) within the valve body (9) that can be moved in response to another magnet (75) outside the valve body to contact the pin (49) attached to the piston (31) to move it to the open position. The magnetic forces applied through the valve body affect internal valve operation via the pin (49) attached to the piston (31) and this avoids the danger of noxious fluids escaping through sliding seals or flexible membranes.

摘要： A urine-collecting container-valve assembly (10,13) particularly intended for use when taking urine from the urinal bladder of a patient, particularly a bed-ridden patient. The assembly comprises a container (10), made of thin plastic material, having an inlet port which accommodates a non-return valve arrangement (13). The valve arrangement (13) is housed in a valve housing (15) having an inlet and an outlet. Arranged in the interior of the valve housing (15) is a perforated plate-like element (16) which extends transversely to the longitudinal axis of the valve housing in liquid-tight abutment with the walls of the housing (15). The housing (15) also has arranged therein a pressure-activated buoyant body (20) which is freely movable between the mutually opposing surfaces of the plate-like element (16) and the bottom wall of the valve housing (15). The invention is characterized by means (23) which co-act with the buoyant body (20) in a manner to guide the body (20) axially during its movement from one terminal position to another terminal position.

摘要： The present invention concerns a flow regulator for gaseous substances, particularly a flow regulator intended for air in air-conditioning and ventilation installations, for maintaining the volumetric flow of the gaseous substance at desired magnitude with sufficient accuracy when the differential pressure acting across the flow regulator varies within given limits. The flow regulator comprises an envelope and a regulating member turnably disposed in the flow passage confined by the envelope. The torque produced by the flow of gaseous substance on the regulating member and on the other hand a countertorque dependent on the position of the regulating member cause the regulating member turning in the flow passage to assume a position of equilibrium such that the requisite pressure drop is obtained for maintaining the volumetric flow rate at predetermined magnitude. The regulating member is substantially slightly curved at least in the flow surface facing the incoming flow of the gaseous substance. The turning angle between the initial and ultimate positions of the regulating member is substantially the same at volumetric flows of different magnitudes when the differential pressure range is the same. The initial and ultimate positions of the regulating member are dependent on the magnitude of the volumetric flow when the differential pressure is the same.

摘要： The fluid delivery system includes a pressurizing device for delivering a pressurized injection fluid, a low pressure fluid delivery system, and a pressure isolation mechanism adapted for fluid communication with the pressurizing device and low pressure fluid delivery system. The pressure isolation mechanism includes a housing defining an inlet port, an isolation port, and an internal cavity. The housing defines a seal seat in the internal cavity between the inlet port and isolation port. A valve member is disposed in the internal cavity. The valve member is free floating in the internal cavity and is adapted to engage the seal seat. The valve member has an open position permitting fluid communication between the inlet port and isolation port, and is fluid flow responsive to fluid flow in the inlet port to engage the seal seat and attain a closed position preventing fluid flow between the inlet port and isolation port.
