Abstract
A pressure regulating valve has a valve chamber having an inlet for connecting to a pressure source, a discharge chamber communicating through a valve opening with the valve chamber, a valve member, a valve seat surrounding the valve opening, a valve closing spring which presses the valve member against the valve seat with an adjustable spring force, and a throttling surface arranged downstream of the valve opening so that between the valve member and an inner wall of the discharge chamber, a pressure is formed at the valve member which counteracts the spring force.
