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.

摘要： A hydraulic motor having pistons, some of which are in a working phase and some are in a non-working phase, whereby the pistons are adapted to rotate the piston hydraulic motor's shaft or casing. To the piston hydraulic motor there are at least two working pressure medium channels, whereby the piston hydraulic motor can be connected for full volume or partial volume. In full volume, all the pistons in the working phase can be brought into the working phase in the motor by a pump's working pressure, whereas in the case of partial volume flow only some pistons can be brought into the working phase by the working pressure. The piston hydraulic motor comprises an actuator, which can close one of the piston hydraulic motor's pressurized inlet channels when the pressure in the other pressure medium channel falls below a certain critical value.

摘要： A cam motor apparatus A is configured such that a cylinder block (2) rotating together with an output shaft (10) is internally provided with a plurality of cylinders (5, 5, . . . ) formed radially in a direction orthogonal to a rotational axis (X) of the cylinder block (2) and pistons (6) respectively housed in the cylinders are reciprocated by the action of working oil distributed thereto by a distribution valve (7) thereby rotating the output shaft. The cam motor apparatus A further includes a selector valve (9) for selectively communicating each of the cylinders with a supply passage (81) or a discharge passage (82) for working oil through the distribution valve. When the selector valve is in a low rotational speed position, working oil is supplied to and discharged from all the cylinders. On the other hand, when the selector valve is changed into a high rotational speed position, working oil is supplied to and discharged from a half of the cylinders and pressurized oil is supplied from a charging pump (16) to the remaining cylinders.

摘要： A hydraulic motor with propulsion members located between an eccentric cam associated with a shaft and a counter-element. The propulsion members consist of two elements slidable telescopically with respect to one another in the longitudinal direction and having annular bearing shoulders kept pressed against corresponding sliding-contact surfaces of the eccentric cam and the counter-element by springs. The resilient springs are located outside the propulsion members and are arranged between the annular edges and elements for mechanically retaining them.
