Abstract (en)
In a single cylinder high pressure reciprocating force pump of the type used in packaging, batching and homogenizing processes, the barrel (1) of the cylinder is divided into suction and delivery chambers by a piston (13) of which the rod (14) occupies half the cross-sectional area of the delivery chamber (11); the pumped fluid passes through two valves, the first a conventional foot valve (7) in the suction chamber (5), the second incorporated into a cavity (17) formed internally of the piston (13) which lies open to the suction chamber (5) on the one hand and to the delivery chamber (11) on the other.
