摘要： A lubricant pump for supplying lubricant to an internal combustion engine, the pump comprising a housing defining a pump chamber, an inlet which is adapted to communicate with a source of lubricant and which communicates with the pump chamber, and an outlet which is adapted to communicate with the internal combustion engine and which communicates with the pump chamber, the housing also at least partially defining a fluid chamber, a source of fluid under pressure, a solenoid for selectively and alternatively affording and preventing communication of the fluid chamber with the fluid source, and a pumping member for drawing lubricant into the pump chamber in response to communication of the fluid chamber with the fluid source and for forcing lubricant out of the pump chamber in the absence of communication between the fluid chamber and the fluid source.
