Abstract: A hydraulic transmission apparatus having at least one declutchable hydraulic motor having radial pistons and connected via two motor ducts, and a casing duct connected to the inside of the casing. The apparatus further has clutching means that, in order to perform the clutching of the motor, are suitable for bringing a first one of the motor ducts to a “clutching” first pressure that is higher than the pressure in the casing while also making it possible to remove fluid via the casing duct. Disposed on the casing duct, the apparatus further has means for limiting the flow of fluid in said casing duct, in a manner such as to cause the pressure inside the casing to increase during the clutching operation. This apparatus enables clutching to take place gently.

Abstract: The clam-shell bucket of an excavating machine is rotatably connected with the arm or boom of the machine by a hydraulic motor which also provides passages for transmitting pressure fluid from the body of the machine to jacks opening and closing the bucket. Radial cylinder bores in the stator of the motor contain respective pistons and spherical cam followers which engage a radially undulating cam face of the rotor when sequentially supplied with hydraulic fluid by a distributor rotating with the rotor in an axial bore of the stator. The passages for the fluid supply of the bucket jacks extend partly in the rotor and partly in the stator and communicate through a bearing interface remote from the distributor and the axial bore containing the same.

Abstract: A hydrostatic radial piston unit of the cam-lobe type of construction having a non-rotary, stationary shaft defining a rotational axis of the hydrostatic radial piston unit. A non-rotary, stationary casing houses the shaft in a torque proof connection. A rotary casing is provided which is rotary around the rotational axis. A pair of roller bearings supports the rotary casing in a rotatable manner against the stationary casing, wherein the pair of roller bearings is arranged in an axial overlapping area in which the stationary casing and the rotary casing overlap.

Abstract: A hydraulic piston machine including a housing, a shaft that is able to rotate relative to the housing, and a cam secured to one of the housing or the shaft. A cylinder block includes pistons that are able to move in the cylinder block opposite the cam in order to generate relative rotation between the cylinder block and the cam. The cylinder block is linked in rotation to the other of the shaft or the housing. A mechanism forms rotation guide bearings for guiding the rotation of the shaft relative to the housing, which mechanism includes a tapered plain bushing interposed between a housing element and an element linked in rotation with the shaft and in which the tapered plain bushing includes a radial through-slit extending through the entire radial dimension of the bushing.
