PCT No. PCT/FI86/00026 Sec. 371 Date Nov. 13, 1986 Sec. 102(e) Date Nov. 13, 1986 PCT Filed Mar. 19, 1986 PCT Pub. No. WO86/05554 PCT Pub. Date Sep. 25, 1986.The invention relates to a hydraulic motor, in which a rotating motion is generated by a combined effect of a cam ring (2) and roller means (5) connected to the pistons (5) of a cylinder group (3).The object is to provide a new dummy coupling solution for a motor of this kind. To the cylinder group (3), preferably between two cylinders (4), is fastened a generally T-shaped support (8, 9) and round each branch (9) of the T is mounted a spiral spring (11) influencing respective piston (5). One end (12) of each spring influences the piston (5) through a passage (17) formed in the cylinder wall and the other end (13) of the spring leans against the support (8). |
