Patent number: 8753139Abstract: A device for the mechanical fastening and electrical contact with at least one control element (2), having first electrical contacts (9a, 9b), within a housing (3). Mating second electrical contacts (11a, 11b) are arranged on a connecting element (4) which can also be plugged into the housing (3). During assembly, the at least one control element (2) and the connecting element (4) are both plugged into the housing (3) so that such plugging engagement achieves electrical connection between the first electrical contacts (9a, 9b) and the second electrical contacts (11a, 11b) and, at the same time, an interlocked fastening of the at least one control element (2) with the housing (3).Type: GrantFiled: October 29, 2010Date of Patent: June 17, 2014Assignee: ZF Friedrichshafen AGInventors: Markus Moosmann, Michael Linder, Mark Pelzl, Marc Ruhstorfer, Karlheinz Mayr

Publication number: 20140150908Abstract: A pressure control valve unit (10) for a fluid with at least one inlet area (P) and first and second outlet areas (A, T) which can be connected for fluid flow with one another by two mutually coupled seat valves (23, 24). An incoming fluid flow, from the inlet area (P) to the first and second outlet areas (A, T), can be adjusted by way of the first seat valve (23), and a fluid outflow, between the first and second outlet areas (A, T), can be adjusted by way of the second seat valve (24). In this case, a flow-guiding device (26) is arranged, upstream from the first seat valve (23) in the inlet area (P), and imposes a specific flow characteristic upon the inflowing fluid in the area of the first seat valve (23).Type: ApplicationFiled: June 14, 2012Publication date: June 5, 2014Applicant: ZF FRIEDRICHSHAFEN AGInventors: Karlheinz Mayr, Markus Moosmann, Frank Hamma, Hubert Remmlinger

Patent number: 8701707Abstract: A pressure control valve device with at least one inlet area and first and second outlet areas which can be connected by two poppet valves. A flow guide device (21), with inflow and outflow areas (22, 23) for guiding the fluid flowing from the inlet area in a defined manner in the direction of the second poppet valve, is located upstream of the second poppet valve, between the first and second outlet areas. The fluid in the flow guide device (21) passes in the area between the inflow and outflow areas (22, 23) through a plurality of channel areas distributed around the periphery of the flow guide device (21) and separated from one another, which are shaped at least approximately helically and impart an at least approximately vortex-like flow pattern to the fluid flowing in the direction of the second poppet valve downstream of the outflow area (23).Type: GrantFiled: December 8, 2008Date of Patent: April 22, 2014Assignee: ZF Friedrichshafen AGInventors: Markus Moosmann, Frank Hamma, Karlheinz Mayr, Hubert Remmlinger

Publication number: 20140026995Abstract: A valve device having at least one inflow area and first and second outflow areas, which are connected with one another with regard to the flow through two poppet valves. Through the first poppet valve, a fluid inflow from the inflow area to the first and second outflow areas can be adjusted and a fluid outflow, through the second poppet valve between the first and the second outflow areas can be adjusted. The second poppet valve is designed as a cone poppet valve with a cone shaped closure body. Located upstream of the second poppet valve, between the first and the second outflow area, is a flow guide device which is designed to provide the fluid, which flows in the direction of the second poppet valve, with a swirl. The closure body of the second poppet valve has a cone angle of 60°+/?10°.Type: ApplicationFiled: July 19, 2013Publication date: January 30, 2014Inventors: Karlheinz MAYR, Markus MOOSMANN, Frank HAMMA, Hubert REMMLINGER

Patent number: 7905249Abstract: An electromagnetic proportional pressure-control valve of a vehicle transmission which includes a magnet part, a hydraulic part and a spring operatively connecting the magnet part to the hydraulic part. The magnet part includes a coil, an armature and an armature bar. The hydraulic part includes first and second closing elements. The first closing element forms a flat seat and the second closing element a ball seat and the closing elements are opened and/or closed via a tappet rod. When no current is applied to the valve, the second closing element is closed and an gap (ü) in the first closing element is larger than one seventh a nominal width (NW) of the valve. The second closure area (A_2) is larger than a circular area having a diameter corresponding to double the gap and the diameter (s) of the tappet rod is smaller than 0.7 times the diameter (b) of the orifice.Type: GrantFiled: March 2, 2006Date of Patent: March 15, 2011Assignee: ZF Friedrichsafen AGInventors: Karlheinz Mayr, Thilo Schmidt, Markus Moosmann

Patent number: 7516756Abstract: Proportional pressure control valve with a magnetic part and a valve part, the valve part has an inflow opening for the inflow stream, a first outflow opening for the filling stream, and a second outflow opening for the tank volume stream, and has a ball seat, a flat seat with an opening, a closing part for controlling the throughput quantity through the opening of the flat seat, and a stream diverter. The inflow opening faces away from the magnetic part and coaxially to its longitudinal axis, and the outflow openings are constructed on the side wall of the valve part radially to its longitudinal axis, so that fluid flowing from through the valve is exposed to a diversion of a maximum of 90°. The fluid, after flowing through the ball seat and to and through the stream diverter, experiences a diversion of less than 30°.Type: GrantFiled: August 19, 2004Date of Patent: April 14, 2009Assignee: ZF Friedrichshafen AGInventors: Karlheinz Mayr, Thilo Schmidt, Walter Kill, Markus Moosmann

Publication number: 20090065722Abstract: A pressure control valve having valve seats, an electromagnet, a magnetic coil, and an armature coupled to an anchor rod, which are axially slidable for biasing a part against a first valve seat to close a tank edge. A push rod, which is integral with the anchor rod, biases a locking element off a ball seat to open an inlet control edge. The cross-section of the inlet control edge can be modified depending on the temperature such that the cross-section is opened as widely as possible at low oil temperatures. The cross-section of the inlet control edge is reduced at high oil temperatures to the extent that a high valve dynamic of the follow-up slide valve is achieved, and the leakage oil flow is not significantly increased.Type: ApplicationFiled: August 25, 2008Publication date: March 12, 2009Applicant: ZF Friedrichshafen AGInventors: Thilo Schmidt, Markus Moosmann, Karlheinz Mayr
