Abstract: The invention relates to a guide block and a method for embodying divisions on a slide plane (22) of a guide block blank (47). The divisions (25) are applied to the guide block blank (47), then a base surface (26) for the slide plane (22) on the guide block blank (47) is pre-prepared. After introduction of a material (41) for application to the base surface (26), a local fusion of the introduced material (41) is carried out, by means of a non-contact heat input (35). Particular forms for the divisions (25) are generated by means of moving the guide block blank (47) and/or a beam (35) of the heat input (34) relative to each other. Finally the support surfaces of the molten material (41) are levelled to generate a planar support surface for the slide plane (22).

Abstract: The invention relates to a scavenging valve for a closed hydraulic circuit. A valve piston (40) is arranged in a longitudinally displaceable manner in a clearance (36) in a valve housing (35). Said scavenging valve (21) has at least three pressure spaces (41, 42, 43) which are constructed in an axially consecutive manner. Two of said pressure spaces (41, 42, 43) can be connected to one another other at a time in dependence upon a relative position of the valve piston (40) in relation to the valve housing (35). In order to interrupt the connection between the pressure spaces (41, 42, 43), a sealing element (44, 45), which effects sealing against a valve-seat face (50) constructed in the housing, is provided in each case.

Abstract: A hydrostatic machine with a cylinder block (6), within which sleeve holes (28b) are arranged, in which sleeves (28) sit, surrounding piston bores (28a) in which pistons (29) are mounted, such as to be displaced back and forth and the pistons (29) extend into the cylinder block (5) such as to define cylinders (26) with the front ends thereof. According to the invention, the risk of piston seizure can be reduced, whereby the sleeves (28) comprise an axially-defined recess (41) in the outer surface thereof, in the region facing away from the cylinder and the region with the greatest piston radial force, pressing the pistons (29) against the wall of the piston bore.

Abstract: A method of producing a ball-and-socket joint (1) between a slipper (3) and a piston (2) of a piston engine, which includes configuring the slipper (3) with a joint ball (4) at an end opposite a bottom surface (21); configuring the piston (2) with an overmeasure (x) on a lateral surface (2c), providing a hemispherical joint recess (5) with a recess edge (7) that protrudes beyond the maximum diameter (6) of the joint recess (5) for receiving the joint ball (4) and bringing together the joint recess (5) and the joint ball (4), and hot-beading the recess edge (7) into a form in which it grips the joint ball (4). Also provided is a joint formed by the foregoing method.
