20080236967 | Locking Apparatus - A locking apparatus, particularly of a parking brake device for a vehicle with an automatic transmission, which has a piston unit positioned inside a housing and is axially displaced and locked in a pre-defined axial position, and a catch device that automatically activates when the piston unit is locked to hold the piston unit. The catch device has at least one spring arm actively connected with the piston unit when the piston unit is locked, the spring arm abuts the piston unit in locked position with a catch area. The spring arm has a recess in a longitudinal plane of the spring arm. The piston unit penetrates the recess of the spring arm at least approximately in a radial direction with a section that forms the catch area, so that when the piston unit is locked, the catch area within the longitudinal plane of the spring arm. | 10-02-2008 |
20080272322 | Proportional Pressure Control Valve Comprising a Pressure Jump in the Characteristic P/I Curve Thereof - 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 | 11-06-2008 |

20090065722 | PRESSURE CONTROL VALVE - 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. | 03-12-2009 |

20130133767 | PRESSURE CONTROL VALVE DEVICE - 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. | 05-30-2013 |
20140026995 | VALVE DEVICE WITH A FLOW GUIDING DEVICE - 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°. | 01-30-2014 |

20150013800 | FLUID VALVE FOR A VEHICLE TRANSMISSION - A fluid valve, in particular a pressure control valve in a vehicle transmission, has at least one inlet opening and a first and a second outlet opening, which are connected to each other through two part valves that are mechanically coupled to each other. Whereas, by means of the first part valve, a fluid intake is adjustable from the inlet opening to the first and second outlet opening, and, by means of the second part valve, a fluid discharge is adjustable between the first and second outlet opening. At least the second part valve is designed as a poppet valve, with a cone-shaped closing element that features several taper areas, which have varying taper angles. | 01-15-2015 |
20150013802 | PRESSURE CONTROL VALVE WITH CONTROL ELEMENT - The invention relates to a pressure control valve, composed of at least a valve component; situated between a control chamber and a return chamber, the valve component has an orifice, which a control element can close, partially close, or open, and the control element has at least one, at least truncated cone-like first control element region with a truncated cone angle and the orifice is formed by a through opening, which extends through the orifice element and at its end oriented toward the control element, has at least one cone-like, in particular first, orifice region with a cone angle; and the cone angle is greater than the truncated cone angle. | 01-15-2015 |
20150014560 | Electromagnetic Actuator and Fluid Valve with Such an Actuator - An electromagnetic actuator with at least one solenoid coil, one armature, which is magnetically movable by means of the solenoid coil in an armature area and has a first and a second tapering, and a magnetic yoke. The yoke has a first dipping stage in which the first tapering of the armature is dipped upon a shifting of the armature in a direction of actuation, and a second dipping stage in which the second tapering of the armature is dipped upon a shifting of the armature in the direction of actuation. A maximum radial external dimension of the armature in the area of the second tapering is smaller than a minimum radial internal dimension of the second dipping stage. In addition, the invention refers to a fluid valve that is actuated by means of the electromagnetic actuator. | 01-15-2015 |
