摘要： A pump (28) is disclosed. The pump may have a housing (42), a body (46) rotatably disposed within the housing and at least partially defining a plurality of barrels (48), a plurality of plungers (50) associated with the plurality of barrels, and a swashplate (56) tiltable by a swivel torque to vary a displacement of the plurality of plungers relative to the plurality of barrels. The pump may also have a port plate (53) with an inlet port (72), a discharge port (74), and a protrusion (94). The port plate may be configured to engage an end of the rotatable body. The pump may further have at least one piston (90, 92)disposed within the housing and configured to selectively engage the protrusion of the port plate to rotate the port plate and adjust the swivel torque.
摘要翻译：公开了一种泵（28）。泵可以具有壳体（42），可旋转地设置在壳体内并且至少部分地限定多个筒（48）的主体（46），与多个筒相关联的多个柱塞（50）和斜盘（56）可通过旋转扭矩倾斜，以改变多个柱塞相对于多个筒的位移。泵还可以具有带有入口端口（72），排出口（74）和突起（94）的端口板（53）。端口板可以构造成接合可旋转主体的端部。所述泵还可以具有设置在所述壳体内的至少一个活塞（90,92），并且构造成选择性地接合所述端口板的突出部以使所述端口板旋转并调节所述旋转扭矩。
