A mechanical device having a shaft, a sealing device for sealing around the shaft, a housing, and a first abutment means. The sealing device has a carrier means on which a plurality of resilient sealing elements are arranged. The mechanical device further has an enclosure means. The sealing device has a first sealing element with an inner dimension, which is larger than the outer dimension of the shaft. The enclosure means at least partially encloses the first sealing element. After the sealing means has been mounted and compressingly fastened in the mechanical device, the first sealing element is compressed in a first direction (A), axially along the shaft and expanded in a second direction (B), radially towards the shaft. The first sealing element is thus brought to a sealing engagement with the shaft.

Mechanical device with sealing means and method for mounting the sealing means

A hydraulic rotating axial piston engine has a housing enclosing a rotatable cylinder barrel. The barrel has a number of axial cylinders with a number of reciprocating pistons. The pistons reciprocate between two defined end positions, and cooperate with an angled plate in order to obtain the reciprocating movement. The cylinder barrel is rotatable relative to a first axis, which is inclined relative to a second axis of an input/output shaft. The housing has two parts, one part of the housing positions the input/out shaft and a second part includes inlet and outlet channels. The rotation of the cylinder barrel and the input/output shaft is synchronized by means of synchronizing means. A central support pin extends along the first axis between the angled plate and the cylinder barrel. The support pin is at one end axially connected with the angled plate, and at the other end axially connected to the cylinder barrel. The support pin limits axial movement at the cylinder barrel relative to the angled plate.
