VALVE DEVICE, IN PARTICULAR FOR HYDRAULIC BRAKE SYSTEMS WITH ABS OR DRIVE-SLIP CONTROL, AND A METHOD OF ADJUSTING A VALVE DEVICE

摘要

The invention concerns a valve device comprising a valve housing (8) provided with a flow control valve, an electromagnetic actuator (1) arranged in series with the flow control valve in the valve housing (8), a piston (3) which forms the flow control valve and in its rest position creates a clear hydraulic connection between a hydraulic fluid source (4) and a hydraulic fluid consumer (5). The actuator (1) in its rest position is braced against the action of a pressure spring (2) at one end face of the piston (3) and in its operating position can detach itself from the piston (3) to take up an intermediate position which regulates the volume of hydraulic fluid flowing from the hydraulic fluid source (4) to the hydraulic fluid consumer (5). This valve design is simple and reliable. In a further invention, a process involving the use of spacers is disclosed for adjusting a valve device comprising a valve housing (8) into which is inserted a flow control valve with an electromagnetic actuator (1) arranged in series with the flow control valve, and a piston (3) which forms the flow control valve and in its initial position creates a clear hydraulic connection between a hydraulic fluid source (4) and a hydraulic fluid consumer.
