    摘要： An air motor has a source of pressurized air, two air chambers, a pilot valve and a directional control valve. The spool of the directional control valve is of the unbalanced type and includes a piston surface in continuous communication with atmosphere through an exhaust port and a pressurized restricted port in alternating communication with the large end of the spool and the piston surface. The alternating communication of the source of pressurized air through the restricted port is restricted relative to the continuous communication of the piston surface with atmosphere. At the point of shift of the directional control valve, the piston surface is in communication with the source of pressurized air through the restricted port.

    摘要： A pump system includes: a first coupler that receives a common input feed and provides two input feeds of fluid being drawn into the pump system, a second coupler that receives two output feeds and provides a common output feed of the pumped fluid, and a third coupler that receives a common gas feed providing two gas feeds to drive the pump system; two pumps, each having an inlet to receive a respective input feed, an outlet to provide a respective output feed of the pumped fluid, and a gas inlet to receive a respective gas feed so as to cause pumping action to drive the pump; and a base for holding the couplers with straps for attaching the two pump. The common gas feed causes pumping action in the two pumps and provides a constant almost pulsation free flow.

    摘要： The present invention involves, in some embodiments, mechanisms and methods of occluding collapsible tubing with an occluder to prevent fluid flow therethrough. In some embodiments, a tube occluding mechanism is disclosed that includes a bendable occluding member for creating a force that can be applied to a collapsible tube to occlude the tube. In some embodiments, the collapsible tube can be an inlet/outlet tube on a removable pumping cartridge that is coupled to a reusable pump drive component when the system is in operation. In such embodiments, the occluding mechanism can be attached to the reusable component and can be used to block fluid flow to and from the pumping cartridge. In some embodiments, the occluding member can comprises a spring plate which can create a force to occlude tubing when in a relaxed, unbent configuration, and which can be bent to unocclude the tubing. In some preferred embodiments, in a default configuration of the tube occluder mechanism (when no external force is applied to the occluding member) the tubes are occluded, so that the tube occluder mechanism provides a fail-safe configuration preventing fluid flow to and from a pumping cartridge to which the tubes can be connected.

    摘要翻译： 在一些实施例中，本发明涉及用闭塞器封闭可收缩管道以防止流体流过其中的机构和方法。 在一些实施例中，公开了一种管闭塞机构，其包括用于产生能够施加到可收缩管以封闭管的力的可弯曲闭塞构件。 在一些实施例中，可折叠管可以是可拆卸泵筒上的入口/出口管，其在系统运行时与可重复使用的泵驱动部件联接。 在这样的实施例中，闭塞机构可以附接到可重复使用的部件，并且可以用于阻止流入和流出泵送的流体。 在一些实施例中，闭塞构件可以包括弹簧板，弹簧板可以在处于松弛的，未弯曲的构造中时产生阻塞管道的力，并且可以弯曲以排除管道。 在一些优选实施例中，在管堵塞机构的默认配置（当外力不对阻塞构件施加时）管被封闭，使得管封堵器机构提供故障安全配置，防止流体流入和流出 泵可以连接到管道上。

    摘要： A diaphragm pump (1) having a diaphragm (11), a solenoid with a movable magnetic armature (8) as a drive element for the diaphragm (11), and a stop element (9) for adjusting the stroke for the drive element (8). The diaphragm pump includes at least one elastic damper (36) between the drive element (8) and the stop element (9), which elastic damper (36) has at least one compression chamber (26) which is surrounded and formed by at least one elastic boundary wall and by at least one rigid boundary wall of the drive element (8) and/or stop element (9).
