摘要： A method and apparatus for a pump and a pump control system. The apparatus includes pistons integrally formed in a diaphragm and coupled to the diaphragm by convolutes. The convolutes have a bottom surface angled with respect to a top surface of the pistons. The apparatus also includes an outlet port positioned tangentially with respect to the perimeter of an outlet chamber. The apparatus further includes a non-mechanical pressure sensor and a temperature sensor coupled to a pump control system. For the method of the invention, the microcontroller provides a pulse-width modulation control signal to an output power stage in order to selectively control the power provided to the pump. The control signal is based on the pressure within the pump, the current being provided to the pump, the voltage level of the battery, and the temperature of the pump.

摘要： Pump apparatus and method. The pump can include a valve assembly and a diaphragm. In some embodiments, the diaphragm can include a convolute that can deform in order to increase a volume of a pumping chamber to provide an internal fluid bypass when a pressure in the pumping chamber exceeds a bypass pressure. In some embodiments, the pump can include a fluid reservoir at least partially defined by a wall with a flow-restrictive conduit in fluid communication with an outlet chamber. A shut-off switch can include an actuator in fluid communication with the fluid reservoir. The fluid reservoir and the flow-restrictive conduit can substantially isolate the shut-off switch from pressure pulses in the outlet chamber.
摘要翻译：泵装置及方法。泵可以包括阀组件和隔膜。在一些实施例中，当泵送室中的压力超过旁路压力时，隔膜可以包括可以变形的卷曲，以便增加泵送室的体积以提供内部流体旁路。在一些实施例中，泵可以包括至少部分地由具有与出口室流体连通的限流导管的壁限定的流体容器。关闭开关可以包括与流体储存器流体连通的致动器。流体储存器和限流导管可以将截止开关与出口室中的压力脉冲基本上隔离开。
