Abstract

The stator (3) and rotor of a permanent-magnet synchronous motor are accommodated in separate chambers. The rotary movement is transmitted by worm gear (13, 18) and an eccentric crank system (21-23) to a plastic piston (25) sliding in a hollow cylinder (26) defining a variable-vol. chamber (27). The liq. is pumped through inlet and outlet ducts (33, 34) with mushroom-headed valves (35, 36) and helical springs (39, 40), at a constant rate during a controlled number of strokes.
