The present invention provides a novel internal combustion engine design and methods for using the same. The internal combustion engine of the present invention may include two rotors on which the pistons and cylinders and pistons are mounted, respectively. A plurality of cylinders mounted on a cylinder rotor, and a plurality of pistons mounted on a piston rod rotor, where the arrangements of the pistons and cylinders are complementary and each piston is paired with one of the cylinders. The cylinder rotor and the piston rod rotor may be position at oblique angle relative to one another, such that their central axes are located on a same plane, but the axes are not coaxially aligned and intersect on that plane.

A housing of an axial piston device is provided with a drain port for discharging the retained oil to the outside and a supply oil passage for guiding lubricating oil, which has been supplied from an oil source, toward a first hydraulic axial piston member. The drain port is arranged so as to bring about such a retained-oil level that a second hydraulic axial piston member, which is disposed below the first hydraulic axial piston member, is partially or entirely immersed in the retained oil while the first hydraulic axial piston member is not immersed in the retained oil.

A drive device incorporating a hydraulic pump having a swash plate. At least two structural ribs and skirting ribs are located on and extend along the length of the swash plate. A plurality of thrust ribs may be formed on an inner housing surface and adjacent to respective contact surfaces on the swash plate, the thrust ribs being located so that at least one, but fewer than all, of the ribs can be in contact with its respective contact surface on the swash plate at a time, permitting rotation while limiting axial movement of the swash plate. A trunnion shaft includes a free end disposed so as to be accessible from outside the housing through a bore formed therein, and a control arm having a shaft portion extends into and supports the distal free end of the trunnion shaft within the bore.

The invention relates to an axial piston machine comprising a drive shaft, a driving gear non-rotatably connected thereto with one or more driving gear pistons accommodated therein, whose piston stroke is adjustable by a swash plate, wherein at least one return spring acts on the swash plate and at least one adjusting piston is supported on the swash plate via an adjusting lever, a first and/or second stop is provided for the adjusting piston to limit the swivel angle of the swash plate, wherein a first stop is formed by the bottom of the blind hole within the connecting plate and/or a second stop is formed by a flat protrusion of the housing in the vicinity of the blind hole.
