Title: High pressure drive unit, control or pump - has reciprocating pistons on timed basis and activated and controlled by fluid pressure
Inventor: EICKMANN KARL
IPC: F04B11/00
Filed: 1991-01-30
Abstract: The coupling (577), of the water deivery piston (578) is connected to a connecting rod (5 or 6) which is an extension of smaller dia. of the reciprocating piston (8 or 9) of larger dia. in the cylinder (14,15).
