20090013864 | Connecting Plate of a Hydrostatic Machine and Method for Producing the Connecting Plate - The invention relates to a connecting plate and to a method for producing connecting plates of hydrostatic machines. The connecting plate is cut to length from a previously produced extruded profile to give connecting plate blanks and is then finished. | 01-15-2009 |
20090199705 | AXIAL PISTON MACHINE AND CONTROL PLATE FOR AN AXIAL PISTON MACHINE - In the case of a control plate for an axial piston machine having at least two control openings ( | 08-13-2009 |
20090288552 | HYDROSTATIC AXIAL PISTON MACHINE - The invention relates to a hydrostatic axial piston engine with a cylinder drum ( | 11-26-2009 |
20110252958 | Machine Housing of a Hydraulic Machine - A machine housing of a piston machine is disclosed. The machine housing is formed in two parts. The machine housing has a main housing which is closed off by a connection plate. Here, the connection plate is screwed to the main housing by means of a plurality of screws, and is positioned with low tolerances with respect to said main housing by means of two centering pins. Here, the centering pins are arranged with twofold rotational symmetry with respect to a shaft axis of a drive shaft of the piston machine. In contrast, screw positions do not have rotational symmetry with respect to said shaft axis. This prevents incorrect mounting of the connection plate. | 10-20-2011 |
20130092250 | Valve Assembly with Adjustable Spring Preload and Tool Kit for Adjusting the Spring Preload - A control valve assembly includes a valve body which is pre-stressed in a direction by a control spring assembly. The spring preload of the control spring assembly is adjustable by an adjusting device which is completely accommodated in the valve box or a fitted housing part. | 04-18-2013 |
20130205989 | Axial Piston Machine having a Retraction Plate, and Method for the Production Thereof - An axial piston machine comprises a cylinder drum in which a multiplicity of pistons are arranged in a longitudinally displaceable manner. The pistons are supported, via sliding blocks, on a running surface which is inclined relative to the cylinder drum axis. The sliding blocks are held, at that side thereof which faces away from the running surface, by means of a retraction plate. The retraction plate is produced from processed sheet metal in a non-cutting punching and stamping process. | 08-15-2013 |
20130239796 | HYDROSTATIC AXIAL PISTON MACHINE - An adjustable hydrostatic axial piston machine of swash plate design includes an actuating apparatus with a cylinder/piston unit and an actuating spring. The actuating apparatus is configured to adjust a pivot cradle of the axial piston machine. The actuating spring engages around at least one axial section of the cylinder/piston unit. | 09-19-2013 |
20140265079 | Spring Return Apparatus for an Axial Piston Machine of Swash Plate Design for Elastically Prestressing Sliding Pads Against the Swash Plate, and Axial Piston Machine having a Spring Return Apparatus of this Type - A spring return apparatus for elastically prestressing sliding pads against a sliding bearing face of an axial piston machine. The sliding pads are positioned on working pistons mounted axially movably in cylinders of a cylinder barrel that drives a drive shaft including a spring plate and a supporting plate. The spring plate includes a ring region surrounding a central opening, and levers extending radially from the ring region. The levers are arranged spaced apart or distributed uniformly in the circumferential direction, and are elastically flexible and/or elastically pivotable in the axial direction. Every two adjacent levers delimit a receiving region for receiving a tapered section of a working piston or a sliding pad. The supporting plate has a circular ring-shaped supporting region configured to support radially outer end sections of the levers if the supporting plate is arranged concentrically with respect to and axially adjacently to the spring plate. | 09-18-2014 |
