ABSTRACT:
An electromagnetic pump has a solenoid reciprocating a piston that abuts the ball of a first, one-way ball valve coaxially aligned with the piston axis. In the abutting position the piston closes the valve and provides a pump chamber of very small volume. An second, one-way outlet valve is located orthogonal to the first valve to provide a compact structure and further minimize the volume of the pump chamber. A plurality of these inlet valves can be arranged so the pistons are parallel and activated by a single, solenoid activated piston, with the outlet valves being radially orientated to provide a compact structure that simultaneously provides precise fluid amounts to a plurality of locations, such as multiple pistons of a two cycle engine.
