摘要： An exemplary pump includes a pump housing defining a pump cavity, a movable pumping member situated in the pump cavity, and at least one pressure-absorbing member located inside the pump housing. The housing also has an inlet and an outlet, and includes at least one interior non-wearing location that contacts liquid in the pump housing when the pump housing is primed with the liquid. The movable pumping member, when driven to move, urges flow of the liquid from the inlet through the pump cavity to the outlet. The at least one pressure-absorbing member is located inside the pump housing at the non-wearing location and contacts the liquid. The pressure-absorbing member has a compliant property to exhibit a volumetric compression when subjected to a pressure increase in the liquid contacting the pressure-absorbing member, the volumetric compression being sufficient to alleviate at least a portion of the pressure increase.

摘要： An exemplary pump-head includes a pump housing having first and second housing portions forming a pump-cavity and a magnet-cavity. The pump-cavity contains a movable pumping element, and the magnet-cavity contains a driven magnet coupled to the movable pumping element. The magnet is driven by a moving external magnetic field, which correspondingly moves the pumping element in the pump-cavity in a pumping manner. The second housing portion has inlet and outlet ports and defines at least respective portions of the magnet-cavity and pump-cavity. The first housing portion is detachable from the second housing portion to allow the pumping element to be accessed and carried away with the first housing portion, without disturbing the second housing portion.

摘要： A fluid pump having a pump housing that includes at least one expansion joint, provides volume compensation, as needed, to adjust for changes in pressure in the pump housing. Various embodiments automatically and passively reduce static pressure in the pump housing associated with a freezing event, thereby preventing damage to the pump head. Volume compensation is achieved by employing, in each expansion joint, a dynamic seal that allows relative movement of two portions of the pump housing, and a bias that provides a selected counter-force to the movement of the housing portions. The subject pumps are particularly suited for use in automotive and other rugged applications, in which fluid pumps may experience recurring freezing events.

摘要： An exemplary magnetically-driven fluid pump includes a magnet housing (“cup”) that enables one or more sensors to be in indirect (“non-wetted”) contact with the pumped fluid while avoiding the static seals normally required with sensors that are mounted to a fluid conduit or chamber and extend into the fluid pathway. Sensors may be used for monitoring the fluid or for feedback control of the pump. By coupling sensors directly to electronic circuits that control the pump, the number of wires located outside the motor housing is minimized, making the assembly more rugged. This is particularly advantageous in hazardous environments or submerged applications. Pumps and hydraulic systems disclosed exhibit fewer leaks under more aggressive pumping conditions and while providing improved pump performance, compared to conventional pumps and systems.
摘要翻译：示例性的磁驱动流体泵包括磁体壳体（“杯”），其使得一个或多个传感器能够与泵送的流体间接（“非润湿”）接触，同时避免了安装的传感器通常需要的静态密封到流体导管或腔室并延伸到流体通路中。传感器可用于监测流体或用于泵的反馈控制。通过将传感器直接耦合到控制泵的电子电路，位于电动机壳体外部的电线数量最小化，使组件更坚固。这在危险环境或潜水应用中特别有利。所公开的泵和液压系统在更积极的泵送条件下表现出更少的泄漏，并且与传统的泵和系统相比提供改进的泵性能。

摘要： A hydraulic circuit includes a pump in fluid communication with a reservoir containing a liquid to be pumped. The pump includes an inlet and an outlet. The hydraulic circuit also includes a venturi pump in fluid communication with the reservoir and with the outlet of the pump, and an injection valve including a cooling feature. The injection valve is in fluid communication with the outlet of the pump, and is configured to dispense liquid supplied to the injection valve by the pump. The cooling feature is in fluid communication with the venturi pump. The pump is configured to produce a first flow of liquid, and the hydraulic circuit is configured to supply a first portion of the first flow of liquid to the injection valve for dispensing by the injection valve and a second portion of the first flow of liquid to the venturi pump.

摘要： Pumps are disclosed that include a pump housing and at least one movable pumping element situated in the housing. The pumping element(s) are magnetically driven by magnetically coupling an external magnet driver (e.g., a stator) to a driven magnet located in the housing. A control circuit selectively operates the stator and a heat-producing element, so as to energize the heat-producing element especially in a potential freezing condition when the pump is not being otherwise operated. Thus, the fluid in the pump is prevented from freezing, and freeze-related pump damage is avoided. The heat-producing element can be the stator itself energized differently from when the stator is used for driving the pump.
