摘要： A hydraulic radial piston engine which comprises a lifting ring which is fixed to the casing, a rotor mounted opposite the lifting ring such that it can be rotated about an axis of rotation, a large number of piston seats aligned radially in the rotor with respect to the axis of rotation, a large number of pistons, each of which is displaceably mounted in a piston seat and which, over at least part of their length, have a guiding and sealing cross section that deviates from a circular shape and which is coincident with a guiding and sealing cross section of the piston seats which deviates correspondingly from the circular shape and remains constant as far as the outside of the rotor, and circularly cylindrical rollers which are borne by the pistons in bearing seats and aligned with their axis of rotation in the direction of the axis of rotation of the rotor, to support the pistons on the lifting ring. The rollers have two end faces which run at right angles to their axis of rotation, and face away from each other. The invention is based on the object of developing a hydraulic radial piston engine which has the features of the preamble of patent claim 1 in such a way that, with a given overall size, a greater swept volume per piston is possible, and therefore a greater torque can be produced, and that the rollers are secured in their position in the axial direction in a simple way. The intended object is achieved by the piston seats having two wall sections aligned at right angles to the axis of rotation of the rollers, and by the distance between the two end faces of a roller being only slightly less than the distance between the two flat wall sections of the piston seats.
摘要翻译：一种液压径向活塞发动机，其包括固定到壳体的提升环，与提升环相对安装的转子，使得其能够围绕旋转轴线旋转，大量活塞座相对于转子径向排列旋转轴线，大量的活塞，每个活塞可移动地安装在活塞座中，并且在其至少一部分长度上具有偏离圆形形状的引导和密封横截面，其与活塞座的引导和密封横截面相应地偏离圆形并保持恒定，直到转子的外侧，以及由活塞在轴承座中承载并与其旋转轴线对准的圆柱形滚子转子轴线的方向，以支撑提升环上的活塞。滚子具有两个端面，它们与其旋转轴线成直角地延伸，并且彼此面对。本发明基于开发具有权利要求1的前序部分的特征的液压径向活塞式发动机的目的，其特征在于，以给定的总体尺寸，每个活塞的扫掠体积更大，因此更大可以产生扭矩，并且辊以简单的方式在轴向方向固定在它们的位置。目的是通过具有两个壁部分的活塞座来实现的，该两个壁部分与辊的旋转轴线成直角对齐，并且辊的两个端面之间的距离仅略小于两个平坦壁之间的距离活塞座部分。

摘要： An apparatus for moving fluid from a first location to a second location comprises a housing containing a pump body having a central passageway with a fluid inlet and first and second fluid outlets in communication with the passageway. A shuttle having first and second fluid chambers is movable within the passageway of the body between first and second positions. First, second, third, and fourth generally annular shaped fluid passageways provided in the shuttle permit selective fluid communication between the first and second fluid chambers of the shuttle and the inlet and outlet ports of the pump body. First and second inlet passageways provided in the shuttle permits selective fluid communication between the inlet of the pump body and the first and second fluid chambers of the shuttle. A piston is reciprocally movable within the shuttle chambers by a uniquely configured operating mechanism, such as a cam ring. The reciprocation piston functions, not only to control fluid flow through the shuttle, but also functions to move the shuttle between its first and second positions within the central passageway of the pump body.

摘要： A percussion tool includes an actuating piston and a pump. The pump includes: a cam ring, a valve plate, a piston housing, and a piston. The cam ring includes an aperture having a camming surface. The valve plate faces the cam ring and includes a fluid port extending therethrough. The piston housing includes a fluid passage extending therethrough and is disposed within the aperture of the cam ring and rotates within the cam ring. A piston reciprocates within the piston housing. The fluid passage in the piston housing is configured to alternate between being in fluid communication with the fluid port in the valve plate and being isolated from the fluid port as the piston housing is rotated relative to the cam ring and valve plate. The flow port in the valve plate is larger in flow area than the flow area of the fluid passage in the piston housing.
