Abstract: The invention relates to an apparatus (1) and a method for driving a solenoid valve (3), having an evaluation and control unit (10), a PWM apparatus (20) and a current measuring apparatus (AM), wherein, in normal operation, the evaluation and control unit (10) generates a PWM signal (PWM) having a duty ratio (TV) and emits said PWM signal to a magnet assembly (3.1) of the solenoid valve (3) by means of the PWM apparatus (20), wherein the current measuring apparatus (AM) detects a current (I) through the magnet assembly (3.1) resulting from the PWM signal (PWM) and reports said current back to the evaluation and control circuit (10), wherein a current (I) that is above a response threshold of the magnet assembly (3.

Abstract: The disclosure relates to a fluidically controlled pressure switching valve for a vehicle brake system including a valve chamber, which is arranged in a valve interior and into which an inlet opening and an outlet opening open, and a valve closing body, which is movable in the valve interior and which comprises a piston, defining a first piston surface and a second piston surface, and including a closing element. The valve closing body is movable in accordance with a pressure difference between a pressure acting on the first piston surface and a pressure acting on the second piston surface, against the force of a setting spring arranged in the valve interior, between a closed position, in which a fluid connection between the inlet opening and the outlet opening is interrupted, and an open position, in which the fluid connection between the inlet opening and the outlet opening is open.

Abstract: A solenoid valve is disclosed that includes at least one chamber which can be filled with a fluid and which is provided in a housing of the solenoid valve, a closing piston which can be displaced by an actuation device and a spring element which can act against the actuation device. An annular element which divides the chamber into a first and a second sub-chamber is provided, said annular element being at least partially, in particular completely engaged in the axial direction by a closing piston of the solenoid valve arranged in a guide opening of the annular element and comprises at least one fluid passage recess which is different from the guide opening.
