20110186760 | SOLENOID VALVE - The invention relates to a solenoid valve having a valve cartridge, which includes a pole core, a valve insert connected to the pole core, an armature that is axially movably guided inside the valve insert and is coupled to a main closing element, and a valve body connected to the valve insert. The valve body forms a main valve with the main closing element and is disposed between at least one first flow opening and a second flow opening. The axial motion of the armature and of the main closing element opens the main valve against the force of a restoring spring, and the force of the restoring spring closes the main valve.

The sliding element and the armature are connected to each other and are pressure-compensated by a compensating port.

20110198522 | SOLENOID VALVE - The invention relates to a solenoid valve, particularly for controlling the brake pressure of a wheel brake of a slip-controllable hydraulic brake system of a motor vehicle. In known solenoid valves, there is a first hydraulically effective connection of an armature chamber of the solenoid valve to an outlet through the guide of a tappet in a valve insert. The first hydraulically effective connection ends in the form of a blind hole and thus does not permit flushing out gas bubbles which possibly have accumulated in the armature chamber. In order to solve this problem, the invention proposes a second hydraulically effective connection which is arranged away from the guide of the tappet, uncoupled from the first hydraulically effective connection. Thus, a closed pressure medium path is effected within a valve cartridge of the solenoid valve, the closed pressure medium path making possible an effective flushing of the armature chamber and thus a flushing out of gas bubbles. | 08-18-2011 |

The unequal areas of the first and second armature faces create a bias in the servovalve torque motor while allowing the first and second pole pieces to be disposed at equal distances from the armature to define substantially equal air gaps. The inclusion of substantially equal air gaps between the pole pieces and the armature reduces the maximum flux in the armature for the same bias and torque output, compared to conventional servovalve torque motors. The reduction in maximum armature flux decreases armature saturation and improves linearity during operation. | 03-22-2012 |
