摘要： A reciprocating pump and transmission assembly having a one-way clutch is disclosed. The transmission includes an input shaft with an eccentric element, a drive link rotatably connected at one end to the eccentric element and at the other to a driven arm. The driven arm is connected to a driven shaft via a one-way clutch. The oscillating motion of the eccentric drives the drive link and driven arm and the one-way clutch translates that motion into incremental motion of the driven shaft. By changing the stroke length of the drive link various gear ratios between the drive shaft and driven shaft are achieved. The driven shaft then uses a mechanism such as a Scotch Yoke to create reciprocating motion to drive one or more pumping elements.

摘要： Illustrative embodiments of positive displacement pumps utilizing pressure compensating calibration, as well as related systems and methods, are disclosed. In one illustrative embodiment, a method of operating a positive displacement pump includes sensing, with a pressure sensor disposed at a fluid outlet of the positive displacement pump, a back pressure at the fluid outlet, transmitting a pressure signal associated with the sensed back pressure from the pressure sensor to a controller of the positive displacement pump, and identifying, on the controller, a volume of fluid pumped by the positive displacement pump using the pressure signal.

摘要： An electromagnetic vibrating diaphragm pump capable of increasing pump efficiency by increasing the vibration amplitude of the vibration of diaphragms even when the pressure inside a compression chamber is high. Diaphragms are fixed to both end portions of an oscillator having magnets. AC driven electromagnets are provided in a manner to face the magnets of the oscillator. A frame adhered to the outer peripheries of the diaphragms covers the electromagnet side, and pump casings cover the opposite sides. The pump casing includes a compression chamber adjacent to the diaphragm, a suction chamber connected to the compression chamber via a suction valve and an exhaust chamber connected to the compression chamber via an exhaust valve, the suction chamber or the exhaust chamber being connected to the frame via a continuous hole.

摘要： A double diaphragm pump has an electromagnetic drive mechanism in which an electromagnetic coil is located between two permanents magnets of like polarity that are alternately attracted to the electromagnetic coil as the polarity of the electromagnetic coil changes. The electromagnetic coil and the permanent magnets are located within a piston assembly that is caused to reciprocate via the change in polarity of the electromagnetic coil. In a second embodiment, there are a plurality of electromagnetic coils arranged in two adjacent rows that surround a shaft with a set of a plurality of permanent magnets located between each pair of electromagnetic coils.

摘要： Provided is a pumping system that includes a parallel dual chamber pumping mechanism and an attachable disposable cassette. The disposable cassette includes a multi-laminate membrane which facilitates efficient, accurate and uniform delivery of fluids. The multi-laminate membrane is held in intimate contact with the pumping fingers of the pumping mechanism by electrostatic or magnetic attraction, thereby allowing the pump to pull a vacuum without the need for a preloaded elastomeric pumping segment.

摘要： A sequentially activated multi-diaphragm foam pump for a foam dispenser includes a housing with a liquid pump portion and air pump portion secured to the housing. The liquid pump portion has a liquid inlet, a liquid inlet valve, a liquid pump diaphragm, a liquid outlet valve, and a liquid outlet. The air pump portion has a first and second air inlet, a first and second air inlet valve, a first and second air pump diaphragm, and a first and second air outlet. The sequentially activated multi-diaphragm foam pump also includes a mixing chamber that is in fluid communication with the liquid outlet, the first air outlet, and the second air outlet. The liquid pump diaphragm, the first air pump diaphragm, and the second air pump diaphragm operate in sequential order. The liquid pump diaphragm pumps liquid into the mixing chamber, the first air pump diaphragm pumps air into the mixing chamber to mix with the liquid to form a liquid air mixture, and the second air pump diaphragm pumps air into the mixing chamber to mix with the liquid air mixture to form a foamy mixture. The foamy mixture is dispensed through an outlet that is in fluid communication with the mixing chamber.

摘要： The present invention relates to a fluid pump system (64) having a fluid reservoir (21) comprising a first cavity (29) and a second cavity (30) in fluidic communication with each other and adapted to accommodate a biological fluid (7). The fluid reservoir (21) is connected to a fluid-container system (27) and a target (5) is in fluidic communication with the second cavity (30). A pressurization system is adapted to generate a first pressure below ambient pressure in the first cavity (29) and generate a second pressure in the first cavity (29). The second pressure is also applied to the second cavity (30). The fluid pump system (64) thereby causes flow of the biological fluid (7) from the fluid-container system (27) into the first cavity (29), from the first cavity (29) into the second cavity (30), and from the second cavity (30) to the target (5).
