<p>A variable-capacity hydraulic motor capable of being mounted simply on a power shovel without interfering with or projecting outward from a truck frame, and capable of being manufactured easily. The variable-capacity hydraulic motor (M') has a valve plate-turning means including a piston rod (69) which is inserted through an end cover (57) so that the piston rod (69) intersects at a right angle the axis of a driving shaft (44), and moves slidingly in its own axis, and a pin (71) for engaging the piston rod (69) with a valve plate (59) fixed to a cylinder block (60). Accordingly, the end cover (57) can be secured directly to a case (50) so that the end cover extends at a right angle to the axis of the driving shaft (44).</p> |
