柱塞泵是往复泵的一种，归于体积泵，其柱塞靠泵轴的偏疼滚动驱动，往复运动，其吸入和排出阀都是单向阀。当柱塞外拉时，工作室内压力降低，出口阀关闭，低于进口压力时，进口阀翻开，液体进入；柱塞内推时，工作室压力升高，进口阀关闭，高于出口压力时，出口阀翻开，液体排出。当传动轴股动缸体旋转时，斜盘将柱塞从缸体中拉出或推回，完结吸排油进程。柱塞与缸孔构成的工作容腔中的油液通过配油盘分别与泵的吸、排油腔相通。变量安排用来改动斜盘的倾角，通过调度斜盘的倾角可改动泵的排量。9510290354AZ-P-F-12-011-LRR12MB-S03549510290355AZ-P-F-12-016-LRR12MB-S03549510290356AZ-P-F-12-022-LRR12MB-S03549510290357AZ-P-F-12-019-LRR12MB-S03549510290358AZ-P-F-12-008-LPR12MB-S03549510290359AZ-P-F-12-014-LRR12KB9510290360AZ-P-F-12-004-RRR12KB9510290361AZ-P-F-12-005-RRR12KB9510290362AZ-P-F-12-008-RRR12KB9510290363AZ-P-F-12-011-RRR12KB9510290364AZ-P-F-12-014-RRR12KB9510290365AZPF-12-016RRR12PB-SO5569510290366AZ-P-F-12-019-RRR12KB9510290367AZ-P-F-12-004-LRR12KB9510290368AZ-P-F-12-005-LRR12KB9510290369AZ-P-F-12-008-LRR12KB9510290370AZ-P-F-12-011-LRR12KB9510290371AZ-P-F-12-019-LRR12KB9510290372AZ-P-F-12-022-LRR12KB9510290373AZ-P-FF-12-008/008-RRR12KB9510290386AZ-P-F-12-022-LRR12PB-S0012德国PGH齿轮泵rexroth齿轮泵力士乐***)
