Abstract
A hydraulic motor comprising a fixed case, a cam, a cylinder block having radial cylinders, an internal fluid distributor having distribution ducts, a braking device comprising a dog clutch, and a control piston. The motor is a slow motor having two distinct operating cylinder capacities. An annular space is formed in the case around the distributor beside the radial face of the cylinder block adjacent to the distributor, the first series of teeth of the dog clutch and the control piston are disposed in said annular space, the second series of teeth being secured to the radially-extending face of the cylinder block in the vicinity of the radially-outer periphery of said radially-extending face.
