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： 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： Embodiments of the invention provide a method of controlling a pump. The method includes sensing a pressure in the pump and entering a low-flow mode when the sensed pressure in the pump is greater than a low pressure threshold. The method also includes reducing power to the pump when the sensed pressure is greater than a shut-off pressure during the low-flow mode and there is flow through the pump until the sensed pressure is less than the shut-off pressure. The method further includes turning the pump off when in the low-flow mode the sensed pressure is greater than the shut-off pressure and there is no flow through the pump.
