Title: High-pressure reciprocating pump
Inventor: SPEHR GUENTHER
IPC: F02M59/26
Filed: 1991-01-30
Abstract: A high-pressure pump with a plunger (3) reciprocating in a cylinder (1) has cylindrical guide surfaces (11a, 11b) on either side of the inlet/outlet port (4a, 4b). The guide surfaces (11a, 11b) have an axial length of 0.05 to 0.5 times the plunger diameter (d). Upstream of the first guide surface (11a) and downstream of the second guide surface (11b), in the direction of pump drive, there is a first and second annular recess (10, 13), respectively. This arrangement provides the advantage that under high pump pressure the plunger (3) emerges from the guide surfaces (11a, 11b), so that the plunger surface areas exposed to unilateral side forces are reduced. This prevents the plunger from canting and possibly seizing.   <IMAGE>
