摘要： A hydraulic power control system includes an engine driving a variable displacement pump. The variable displacement pump is fluidly connected to a first passageway and a second passageway, and has a selectively variable displacement that is adjustable in response to a pump displacement command signal. A hydraulic motor fluidly connected to the first and second passageways operates by a flow of hydraulic fluid originating from the pump. A controller receives an engine speed signal and adjusts pump displacement based on the engine speed signal to reduce the rotation speed of the pump when an overrun condition is present.

摘要： A method for synchronizing pistons within linear pumps of a variable dispense ratio system comprises operating first and second pistons, controlling the first and second pistons, and reversing direction of one of the first and second pistons. The first and second pistons are operated within first and second cylinders so that the first piston moves at a slower speed than the second piston to produce a variable dispense ratio. The first and second pistons are controlled to reverse directions whenever one piston reaches an end of its respective cylinder to produce pumping. One of the first and second pistons reverses direction before either piston reaches an end of its respective cylinder to adjust the synchronicity of the pistons.

摘要： The pump is provided with a plurality of pumping chambers and electrically activatable valves. An elastic membrane is arranged in each pumping chamber and divides the same into a first and a second chamber section. Each valve is connected to the second chamber section of a pumping chamber. When a pressure drop is applied over the valve and the valve is activated (i.e. opened), the pressure in the second chamber section changes, which causes the membrane to move, which in turn leads to a change of the volumes of both chamber sections. This e.g. allows to pump well-defined amounts of fluid from the chamber sections to a drug dispensing device.
