摘要： A disposable pump unit (100) for receiving and metering a predetermined volume of fluid has a body with a surface at which opens the mouth of a cavity (7) formed in the body. An inlet port (4) for the fluid opens at the surface adjacent to the mouth of the cavity (7) and a plurality of outlets (9) are provided in the cavity (7) that open to a fluid flow passageway extending through the body and connecting the cavity (7) to an outlet port (10). A flexible membrane (8) overlies the cavity (7), the inlet port (4) and the outlet port (10) and is sealingly secured at its periphery to the surface. A re-usatile pump actuating unit (200) is co-operable with the pump unit (100) to position the membrane (8) between the cavity (7) in the pump unit (100) and a matching cavity (21) in the actuating unit (200). The membrane (8) is towards and away from the cavity (7) by connecting the cavity (21) to a source of positive and negative fluid pressure via a port (18). The actuating unit (200) has an armature (19) operable to displace the membrane (8) to close the inlet port (4) when the outlet port (10) is open and an armature (20) operable to displace the membrane (8) to close the outlet port (10) when the inlet port (4) is open. In use, the pump unit (100) draws fluid into the cavity (7) when the inlet port (4) is open and a negative fluid pressure is applied to the chamber (21) and pumps the fluid out of the cavity (7), when the inlet port (4) is closed and a positive fluid pressure is applied to the chamber (21).

摘要： A double diaphragm pump including an air manifold, two air chambers to either side of the air manifold, two pump chambers to either side of the air chambers and diaphragms extending between the air chambers and pump chambers are stacked together in horizontal assembly. Intake and discharge manifolds span this distance to intake and exhaust ports associated with the pump chambers. One-way valves having valve bodies with passages therethrough are arranged between the manifolds and the pump chambers. The valve bodies have inlet mounting surfaces and outlet mounting surfaces with circular attachment flanges radially extending from these mounting surfaces. The circular attachment flanges each define a central axis which on each valve body are parallel and laterally displaced from one another. Concavities extend inwardly from the valve bodies from the inlet and outlet mounting surfaces. The angle between the central axis in the direction of the adjacent mounting surface and the surface of either concavity is acute and does not exceed approximately 60°.

摘要： A fluid driven pump. One embodiment of the fluid driven pump may include first and second diaphragms supported within a housing assembly such that first and second fluidtight expansion chambers are defined within the housing. The pump may have a first exhaust valve movably supported in a first exhaust valve cavity in fluid communication with the first expansion chamber and an exhaust port in the housing assembly. In addition, the pump may have a second exhaust valve movably supported in a second exhaust valve cavity in fluid communication with the second expansion chamber and the exhaust port. A flow control system may be supported by the housing assembly and be couplable to a source of pressurized control fluid. The flow control system may control flow of pressurized fluid into and out of the first and second expansion chambers such that pressurized fluid entering the first expansion chamber flows through a first passage in the housing assembly independent from a first exhaust passage which connects the first exhaust valve cavity to the first expansion chamber and such that pressurized fluid entering the second expansion chamber flows through a second passage in the housing assembly independent from a second exhaust passage connecting the second exhaust valve cavity to the second expansion chamber.

摘要： A double diaphragm pump including a pump housing, first and second pump diaphragms, an inlet manifold, an outlet manifold, and an air motor. The air motor includes a spool valve having a valve housing, an insert surrounded by the valve housing, and a spool. The valve housing and the insert cooperate to at least partially define a valve chamber, and the spool is slidably positioned within the valve chamber. The spool includes a seal engaging an inner surface of the insert and delimiting the valve chamber into valve subchambers. Movement of the spool within the valve chamber selectively communicates pressurized fluid to one of the diaphragms to move the associated diaphragm, thereby pumping fluid through the pump.

摘要： A reduced icing valve for an gas-driven motor and a reciprocating double diaphragm pump is provided having a shiftable valve for alternatively supplying a motive gas through first and second supply ports to opposed first and second power pistons in opposed motive gas chambers, respectively, and for effecting alternating exhaust of the chambers. The shiftable valve is provided with an insert that deflects, away from the shiftable valve, air entering from each of the bypass valves until the bypass valves are fully actuated by the exhaust gas from the motive gas chambers. The shiftable valve is further provided with bypass valves independent of and intermediate the shiftable valve and each of the first and second motive gas chambers for bypassing the shiftable valve by exhaust gas from the motive gas chambers. The bypass valves are further actuated in an opposing direction by a supply source of motive gas to the chambers.

摘要： A pneumatically-actuated reciprocating fluid pump and shuttle valve combination operates in an “air-assist” mode and a “non-air-assist” mode. In the non-air-assist mode, the shuttle valve is shifted by a blast of pressurized supply air from the pneumatic chamber in its pumping stroke as the flexible diaphragms and drive shaft reach the end of their pumping stroke. This blast of pressurized air used to shift the shuttle valve has the effect of reducing the air pressure in the pneumatic chamber immediately prior to the point in time that the drive shaft reaches the end of its stroke in order to provide a cushioning effect at the end of each pumping strokes cycle, in order to lessen the effect of the drive shaft and diaphragms abruptly reversing direction at full air pressure. In the air-assist mode, a secondary source of compressed air is utilized to shift the shuttle valve, rather than drawing pressurized air from the pneumatic chamber during its pumping stroke. In the air-assist mode, the full effect of the pressurized air to the pump is directed to pump fluid through the pump, and is not lessened by tapping a minute amount compressed air at the end of each pumping stroke cycle for shifting the shuttle valve.
