Abstract: The invention concerns a variable pump or hydraulic motor with a drive shaft with a first axis of rotation and first plungers connected to the drive shaft and rotatable around the first axis of rotation. A port plate mounted in the housing can rotate around an axis intersecting the first axis, for adjusting the stroke volume. The port plate positioning drive comprises two counter-acting hydraulic actuators acting on the port plate in the direction of the first plungers.

Abstract: The invention relates to a hydraulic device having, in a housing, a rotor, which can rotate about a first axis, with pistons and chambers on both sides of the rotor, which can rotate about a second axis and are formed by a cylindrical wall and a piston. The cylindrical walls are rotatable about a second axis (m1 and m2) and the first axis, such that, during rotation of the rotor, the volumes of the rotor chambers on one side of the rotor and the rotor chambers on the other side of the rotor alternatively have a minimum value.

Abstract: To provide an attachment structure of a swash plate support, that is, an attachment structure which suppresses an unstably fixed state of the swash plate support and realizes easy attachment and detachment of the swash plate support to and from a casing. A casing of a piston pump and a swash plate support which is attachable to the casing include a displacement preventing device and a rotation preventing device. In the swash plate support and the casing, since an engaging pawl portion of the displacement preventing device engages with an engaging portion, relative displacements in a first direction and a second direction along the rotational axis are prevented, and since a pin member of the rotation preventing device fits in the pin fit hole, relative rotations around the rotational axis are prevented.

The expander may have a cylindrical barrel with a plurality of cylinders arranged in the circle and open at one end face of the cylinder barrel, which end face is sealed closed by a valve plate. The cylinder barrel and valve plate allow relative rotation therebetween to drive an output shaft, driven by compressed gas from the compressor.

Abstract: An internal combustion engine having two rotating cylinder blocks in each of which is formed a plurality of cylinders to receive portions of pistons that extend partially into each cylinder block. The cylinder blocks are angled relative to one another and the pistons are similarly angled to cause variation in the free volumes of the cylinders as the cylinder blocks rotate. A support shaft passes through the centers of the cylinder blocks to provide support for the cylinder blocks via bearings on the support shaft. Air is introduced into the cylinders via central cavities in the cylinder blocks and fins and slots are formed on, and in, respectively, the interior walls of the cavities to impart rotation to air in the cavities. A series of rings, through which the cylinders pass, are formed on the end of each cylinder block that faces away from the other cylinder block to circulate cooling air drawn into a housing in which the blocks are mounted about the cylinders.
