Patent number: 9157539Abstract: A pressure-control valve device for a fluid, having at least one inlet area and first and second outlet areas that can be flow-connected to one another by two seat valves coupled to one another, in which a fluid flow from the inlet area to the first and second outlet areas can be adjusted by the first seat valve and a fluid flow between the first and second outlet areas can be adjusted by the second seat valve. The first seat valve is designed as a valve aperture with a valve opening and a valve control edge and with a ball-shaped closing element that co-operates with the valve control edge. The valve opening and the ball-shaped closing element are designed such that the ratio of the diameter of the valve opening to the diameter of the ball-shaped closing element is equal to at least 0.75.Type: GrantFiled: November 27, 2012Date of Patent: October 13, 2015Assignee: ZF Friedrichshafen AGInventors: Karlheinz Mayr, Markus Moosmann, Frank Hamma, Hubert Remmlinger

Patent number: 6904934Abstract: A proportional pressure adjustment valve is described which comprises one valve part with inlet and outlet openings (4) and at least one closing mechanism (7) for control of a valve (12), the same as a magnet part having one magnet core, one magnet coil and one displaceably disposed magnet armature. An actuating element (11) cooperates with the armature, actuating the spherical closing mechanism (7). The hydraulically active cross section of the valve (12) is essentially determined by the length of the valve (L), the diameter of the valve (D) and th diameter (d) of the part (13) of the actuating element (11) which penetrates into the valve. According to invention, the ratio of the length of the valve (L) to the diameter of the valve (d) is less than 2.0.Type: GrantFiled: July 13, 2001Date of Patent: June 14, 2005Assignee: ZF Friedrichshafen AGInventors: Wolfgang Runge, Hubert Remmlinger, Karlheinz Mayr, Wolfgang Schmid, Thilo Schmidt

Patent number: 6895808Abstract: The present invention concerns a method and a device for machine diagnosis and, in particular, for transmission diagnosis in a machine or motor vehicle. The measurement system, according to the invention, comprises a coil (2) wound on a coil core (11), on the surface of which ferritic wear particles (3) to be detected accumulate. Opposite the coil (2) a rotating toothed wheel (6) is arranged which influences the inductance of the coil (2). The output signal of the coil (2) is pulsed with a constant amplitude, the pulse frequency depends on the rotation speed of the toothed wheel (6). Deviations of the amplitude are attributable to the accumulation of ferritic wear particles (3) on the coil (2) and therefore provide a measurement of the condition of the machine or transmission.Type: GrantFiled: July 3, 2003Date of Patent: May 24, 2005Assignee: ZF Friedrichshafen AGInventors: Hubert Remmlinger, Robert Ingenbleek, Gabriele Schuwerk, Rolf Schmitz

Patent number: 6873919Abstract: A method for machine diagnosis and, in particular, for transmission diagnosis of a machine or motor vehicle. The measurement system comprises a capturing magnet (2), on the surface of which the ferritic wear particles (3) to be detected accumulate. A binary measurement signal is produced by a reed contact (1) arranged opposite the capturing magnet (2). This measurement gives an indication of the condition of the machine or transmission.Type: GrantFiled: July 2, 2003Date of Patent: March 29, 2005Assignee: ZF Friedrichshafen AGInventors: Hubert Remmlinger, Robert Ingenbleek, Gabriele Schuwerk, Rolf Schmitz

Patent number: 6837477Abstract: A proportional pressure-regulator valve comprising a load-dependent control step and a method for the load-dependent regulation of a pressure level of a pressure medium with one proportional pressure-regulator valve. The load-dependent control step is obtained with a proportional magnet (1) having at least two gaps (10, 12) for regulating the magnetic force. The size of the gaps (10, 12) can be adjusted independently of each other. While a first gap (!2) is current-dependent regulated, the size of the second gap (10) can be regulated via a pressure force adaptable in proportion to a load requirement in the hydraulic circuit.Type: GrantFiled: September 17, 2003Date of Patent: January 4, 2005Assignee: ZF Friedrichshafen AGInventors: Karlheinz Mayr, Walter Kill, Thilo Schmidt, Gunter Philipp, Hubert Remmlinger
