Fluid flow and pressure regulating hydraulic solenoid valve for motor vehicle`s braking system, has valve that moves in translation between closing position and opening position, where movement is controlled by piezoelectric disk
Fluid flow and pressure regulating hydraulic solenoid valve for motor vehicle`s braking system, has valve that moves in translation between closing position and opening position, where movement is controlled by piezoelectric disk
The valve has a valve (10) moving in translation between a closing position to contact with a valve seat and an opening position in which the valve is at a distance from the seat. The valve movement is controlled by a piezoelectric part (5) that is in the shape of a disc whose axis is parallel to valve`s translation axis. A needle (6) is fixed to the disk to close an opening (7) connecting high and low pressure hydraulic chambers.
