The invention concerns a radial piston hydraulic engine (10), which includes a rotated box section (11), with which box section (11) a cam ring (12) is connected. The radial piston hydraulic engine (10) includes a fixed non-rotary shaft (14), with which a cylinder body (15) in a fixed position is connected. The radial piston hydraulic engine includes a distributor (13), which is connected with the box section (11) and rotates together with it, whereby through channels located in the distributor a pressurised medium is conducted to pistons (16a1, 16a2 . . . ) of cylinders (P1, P2 . . . ) controlled by the distributing valve, that is, by distributor (13), and that at least some cylinders (P1, P2 . . . ) include in connection with themselves a shut-off valve (70a1, 70a2 . . . ), which is used to make some pistons (16a1, 16a2 . . . ) inoperative. Shaft (14) includes in the same cylinder block (I) at least two control pressure channels (Y1, Y2) for the shut-off valves (70a1, 70a2) of its cylinder body (15), whereby by supplying pressure selectively into a channel (Y1 or Y2; Y1 and Y2) it is possible to make certain cylinders (P1, P2 . . . ) inoperative by directing control pressure to the shut-off valves (70a1, 70a2, 70a3 . . . ).

1. A radial piston hydraulic engine, comprising:a rotatable box section; a cam ring operatively connected to said rotatable box section; a fixed non-rotary shaft having at least two control pressure channels; a plurality of cylinder bodies fixedly connected to said non-rotary shaft, each of said plurality of cylinder bodies having a piston structured and arranged therein; wherein a selected number of cylinder bodies have a shut-off valve in communication with said at least two control pressure channels of said non-rotary shaft; said at least two control pressure channels are structured and arranged to selectively supply a control pressure to said shut-off valves of said selected number of cylinder bodies; whereby when said control pressure is supplied to said shut-off valve a selected number of pistons are deactivated; a distributor connected to said box section and structured and arranged to rotate therewith, said distributor having at least one channel structured and arranged to communicate a pressurized medium from said non-rotary shaft through said shut-off valves to each of said pistons; an oil space located below said piston and in communication with said shut-off valves; an outlet channel formed in said non-rotary shaft and in communication with said shut-off valves; and wherein each of said shut-off valves comprise: a pin having a central annular channel; and wherein said pin is movable between a first position, in which said central channel of said pin is aligned with said outlet channel and permits a communication between said oil space located below said piston and said outlet channel, and a second position, in which said central channel is out of alignment with said outlet channel thereby preventing a communication between said oil space and said outlet channel.
