发明名称 ECCENTRIC DRIVE MECHANISM FOR VOLUMETRIC PUMPS OR MOTORS
摘要 <p>Drive mechanism having stroke member (HG) fixed to shaft (W) of a mechanism having eccentric bearing (HL) which connects stroke member (HG) to coupling member (KG) connected by transverse bearing (QL) to pressure member (DG). Included is pressure source (DQ) for fluid lubricant connected to transverse bearing (QL). This connection includes first passage (K 1 ) extending through stroke member (HG) into eccentric bearing (HL) and second passage (K 2 ) extending from eccentric bearing through coupling member (KG) into transverse bearing (QL). A space arrangement provides for conduction of the fluid lubricant to second passage (K 2 ), this space arrangement having an arrangement permitting a flow of the fluid lubricant between first and second passages The applications has been limited to unidirectional pumps. (K 1 ,K 2 ) only within low pressure phases of the fluid lubricant. Space arrangement is in bearing surface (L 1 ) of stroke member (HG) and extends over part of peripheral section (UN) of stroke member (HG) corresponding to low pressure phase.</p>
