ELECTROMAGNET PUMP Russian patent published in 2008 - IPC F04B17/04 

FIELD: mechanical engineering; pumps.

SUBSTANCE: invention relates to pumps operating on electric energy, particularly, to electromagnetic pumps in which electromagnet using energy of reservoir capacitor is used as drive or power member. Pump consists of electromagnet, water pump housing in form of cylinder, cup with ports, armature with threaded hole, rod with threaded part by which it is turned into threaded hole of armature. Piston is provided with intake valve. Working spring is fitted on rod and it thrusts by one end against piston, and by other end against adjusting nut on thread of thrust bushing fitted onto rod from side of armature and resting against electromagnet housing. Winding is arranged in electromagnet housing. Delivery pipe with fitted in outlet valve is connected to water pump housing. Intake valves are fitted in ports of cup.

EFFECT: increased capacity owing to forming closed space under piston by intake valves which provides filling of space over piston when piston is moved downwards under pressure created in cup by moving piston.
