摘要： Pumpeinrichtung (1) mit einem Antriebsmotor (2) und einer damit gekoppelten Fluidpumpe (3), die ein Pumpengehäuse (42) mit zumindest jeweils einem saugseitigen Zulaufkanal (5) und einem druckseitigen Ablaufkanal (4) aufweist, und mit einem Druckbehälter (7), der kommunizierend mit dem Ablaufkanal der Fluidpumpe verbunden ist. Wenigstens sind zwei Funktionsbaugruppen vorgesehen, in denen der Antriebsmotor (2) mit der Fluidpumpe (3) einerseits und der Druckbehälter (7) andererseits integriert sind, wobei die Funktionsbaugruppen räumlich kompakt zueinander angeordnet und miteinander verbunden sind. Die den Druckbehälter (7) umfassende Funktionsbaugruppe weist einen Rahmen (26,27) auf, der den Druckbehälter formschlüssig umgibt. Der Rahmen (26,27) weist zumindest eine Standfläche (28) zum Stand des Druckbehälters auf dem Untergrund, sowie eine Montagefläche (29) zur Verbindung mit der die Fluidpumpe (3) umfassende Funktionsbaugruppe auf. Der Rahmen (26,27) ist als Kunststoffspritzgussteil ausgeführt.

摘要： In open-circuit hydraulic systems (1), the cross-sections of the supply lines (6) and input valves of the hydraulic pump (3) have to be large, so that sufficient flow flux can be provided.
This hinders a reduction of the size of the pump and the whole hydraulic system.
It is suggested that the supply flow (7) of a hydraulic pump (3) is charged by a second, charging pump (2), to a mid-pressure level (7). The cross-sections of the supply flow areas can thus be decreased.摘要翻译： 在开路液压系统（1）中，供油管路（6）和液压泵（3）的输入阀的横截面必须大，从而可以提供足够的流量。 这阻碍了泵和整个液压系统的尺寸的减小。 建议液压泵（3）的供给流（7）由第二充气泵（2）充入中压水平（7）。 因此可以减少供应流动区域的横截面。

摘要： A vacuum pump capable of pumping solid, liquid and gas, or any combination thereof, including a drive (40) and a manually disengageable pumping system connected thereto. The pumping system is composed of a two- or three-chambered canister (1, 18, 21) within which solids, liquids, and gases can be separated from one another. A highly flexible diaphragm (24), attached to the canister and sealed against it circumferentially, facilitates this separation, when reciprocating and pumping. The components of the pumping system are designed to be disposable, and the two- or three-chambered canister provides for a highly efficient pumping system that is significantly smaller in size than those previously known. The pump is particularly useful for medical applications.

摘要： In one aspect, a bracket for evacuating a storage bag having a one-way valve element is provided that has parallel first and second flat panels that delineate a gap. A bag can be placed into the gap such that the valve element on the bag aligns with an aperture disposed through the first panel. To evacuate the bag, a nozzle of an evacuation device can be inserted through the aperture and pressed against the bag sidewall about the valve element. When the evacuation device is activated, the sidewall of the bag is pulled against the rim of the nozzle and air is drawn through the valve element. In another embodiment, the nozzle can be pressed against the first panel around the aperture. In another aspect, the bracket can be included as part of a handheld evacuation device.

摘要： The invention integrates a filter system into a reciprocating piston pump (10) . This design will eliminate the need for extra connection components, increase the maximum internal pressure allowed due to no danger of the filter loosening, ease maintenance and cleaning while also decreasing the overall size of the system. Because the overall size is smaller, less energy is required to change the pressure throughout the system and thus increase overall efficiency compared to previous designs. The invention is a filter element (29) that inserts and becomes integrated with the upper housing (33) of the pump (10). The filter element (29) is inserted into its own cavity and held in place by upper and lower connectors (23, 27) that threadedly engage with the pump housing (33).

摘要： A portable reciprocating air compressor unit (32a) is driven by an electric motor (58) that is attached to an electrical circuit having a predeterminable current capacity. A manually controllable valve mechanism (68) mounted to an inlet (71) of the compressor, allows for control of the amount of air that a piston (69) draws and compresses during each reciprocation. The amount of electric current used by the electric motor (32a) to drive the piston (69) depends on the amount of air drawn and compressed. A user can therefore control the amount of electric current that the compressor unit (32a) uses.

摘要： Die Erfindung betrifft eine Labor-Pumpeinheit (1) zum Pipettieren, Filtrieren und Absaugen eines gasförmigen oder flüssigen Fluids. Die erfindungsgemäße Labor-Pumpeinheit (1) hat eine Pumpe (3), die saug- und/oder druckseitig mit einer Pipette (4) oder dergleichen Fluidaufnahme lösbar verbindbar ist zum Ansaugen oder Ausstoßen des Fluids. Für die erfindungsgemäße Labor-Pumpeinheit ist u.a. kennzeichnend, dass an die mit der Pipette (4) oder dergleichen Fluidaufnahme einerseits und der Pumpe (3) andererseits verbundene Saugund/oder Druckleitung (6, 7) eine Nebenleitung (9, 10) angeschlossen ist, die zur Atmosphäre hin offen ausgebildet ist und die zur Begrenzung der angesaugten oder ausgestoßenen Luftmenge eine Drosselstelle (11, 12) aufweist. Die erfindungsgemäße Labor-Pumpeinheit (1) wird saug- und druckseitig im "offenen" Pumpenbetrieb mit einem genau eingestellten Leitungsdruck in der Saug- und/oder Druckleitung (6, 7) betrieben, der von der Pumpe (3) nicht über- oder unterschritten werden kann.

摘要： A system for generating a high pressure fluid jet (44) includes a variable pressure pump (22) and a burst resistant delivery tube (36) which safely conducts the pressurized stream to an instrument (40). The pump may include a disposable diaphragm pump cartridge (28) which is driven by a reusable pump (26). The delivery tube may be a coiled hypo tube which enhances flexibility.
