摘要： The pump includes a housing containing a hollow elongated part, a piston arranged to move back and forth inside an elongated part, an inlet port and an outlet port arranged so that a fluid can be sucked through the inlet port into a chamber during an instroke of the piston and expelled through the outlet port during an outstroke. A linearly and/or angularly actuable valve system has a valve holder mounted on the pump housing which includes at least one through-hole extending from the piston chamber to the housing outer surface. The valve holder contains an inlet and/or outlet to alternately connect the inlet and outlet ports of the volumetric pump.

摘要： A radial piston pump has a pump body with two pump chambers lying in a straight line. In the pump chambers pistons reciprocate along this same straight line. The pump pistons are coupled to an actuator which is rotatable about an axis which bisects the straight line, and reciprocates the pistons in opposite directions. Each pump chamber is connected to an intake fluid duct and a discharge fluid duct, and the intake ducts are connected to a common main intake duct and the discharge fluid ducts to a common main discharge duct. An actuator controls operating components which co-operate with valve arrangements for the opening and closing of the fluid ducts.

摘要： A radial piston machine includes a housing, rotor, first braking member, and brake ring with a second braking member. The rotor is mounted in the housing to be rotatable relative to an axis of rotation, and has an end face facing in a direction of the axis of rotation. The first braking member is positioned on the end face. The housing has a body defining a ring-shaped extension relative to the axis of rotation. The brake ring is positioned to surround the extension and is configured to be movable in the direction of the axis of rotation so as to bring the second braking member into braking engagement with the first braking member. The brake ring is further configured to positively engage with an inner radial side of the extension to limit a twisting between the housing and brake ring.
