摘要： A pulsatile pump (P) the outlet of which is infinitely variable between a slow pulsatile flow and increased up to a sharply pulsed flow rate until the pulses run together and a smooth flow results, and which may be varied between wide output pressure and frequency limits. The pump is comprised of a pneumatic control circuit (90), at least two pneumatically isolated compression chambers (61, 63), and a novel inlet/outlet pump cartridge (50) and condition-responsive locking means (300). Operation of the pump is controlled by the use of novel tactile pneumatic response switches (110, 148, 168, 178). Each compression chamber is communicated with a supply of working fluid through the cartridge. Means are provided for varying the operation of the pneumatic circuit and hence the pump. A flow of pressurized fluid (72), such as air or nitrogen, is used as the operating media of the pneumatic circuit, although other fluids may be used. Means for monitoring and adjusting pump system parameters are also provided. The pump operates entirely through the use of pneumatic energy, avoiding the use of electricity.

摘要： A differential pressure motor comprising two working pistons and a rod that move in a hollow space. Walls defining the hollow space have five openings. A valve piston moves between and against the working pistons and can be driven by the working pistons. The valve piston with the five openings forms a valve with which an alternate impact of a first pressure and a second pressure on the working pistons is controllable when the pressures are applied to three of the five openings such that the working pistons periodically move which drives a periodic movement of the valve piston. Also disclosed are a surgical drive system with, a medical lavage system for the debridement of soft tissue and/or bone tissue having, and a medical device for brushing, rasping or sawing soft tissue and/or bone tissue with such a differential pressure motor, and a method for operating a differential pressure motor.

摘要： Reciprocating fluid pumps include a reinforced shaft including an inner shaft and a protective cover. The protective cover at least substantially encapsulates the inner shaft. The inner shaft exhibits a greater resistance to mechanical deformation than the protective cover, and the protective cover exhibits a greater resistance to chemical corrosion by the subject fluid than the inner shaft. Methods of forming a reciprocating fluid pump include forming a reinforced shaft and positioning the reinforced shaft within a subject fluid chamber and between two plungers.

摘要： An apparatus for generating high hydraulic pressure with reduced pulsations, comprising a valve case attached to a motor main body and having a plurality of pneumatic cylinder units arranged therearound, a rotary valve rotatably fitted in the valve case, links each having one end pivoted to the piston of each pneumatic cylinder unit and the other end connected to an eccentric shaft portion provided on a crank shaft or the rotary valve, and hydraulic bases connected directly to the pneumatic cylinder units individually, the hydraulic pressure fluid being caused to flow-out from the hydraulic bases in succession by the rotation of the rotary valve, in such a manner that when the outflow of the fluid from one of the hydraulic bases is about to cease, the fluid starts to flow out from another hydraulic base, and when the flows of hydraulic fluid from the two hydraulic bases combine, the pulsation of the flow from one base is offset by that of the other single flow, making it possible for the hydraulic fluid to uniformly flow out without pulsation.

摘要： A reversing mechanism for a reciprocating pump provided in a common housing or module removably secured to the pump body adjacent to the pump shaft. The module housing includes top and bottom pieces which slide together with suitable tongue and groove elements. The top piece houses a reversing valve, and has a slot on the underside thereof for receiving a yoke member of the reversing mechanism. The sides of the slot form bearing surfaces parallel to the longitudinal axis of the pump shaft. The yoke slides or reciprocates on these bearing surfaces. The bottom piece comprises a support for opposed snap-acting springs. The yoke has a pair of upwardly extending spaced arms for actuating opposite ends of the reversing valve when it reciprocates, and a pair of downwardly extending spaced arms for engaging a transverse pin in the pump shaft as the shaft reciprocates. A central pin in the yoke couples it to the snap-acting springs. A special nested bearing structure is provided for the snap-acting springs. The pump is provided with coded inlet and outlet valve cartridges to preclude the improper assembly thereof within the pump housing.

摘要： A diaphragm air pump assembly pneumatically associated with a vacuum source and an atmospheric air source, comprises two diaphragms interconnected by a vertically extending rod to define two vacuum operational chambers and two pump chambers, two valves for controlling the alternative admission of vacuum to the vacuum operational chambers, and two normally closed valves operable in response to movement of the diaphragms in unison with the rod, each of two corresponding constituent parts being disposed and mounted in a symmetrical arrangement with respect to the central axis of the pump assembly. When the diaphragms are moved in one direction, one of two normally closed valves is opened to admit the vacuum into one of two vacuum operational chambers while admitting atmospheric air into the other vacuum operational chamber. When the diaphragms are moved in the other direction the other normally closed valve is opened to admit the vacuum into the other vacuum operational chamber while admitting atmospheric air into one of two vacuum operational chambers. Thus two pump chambers are alternatively compressed to effect the pumping operation.
