ABSTRACT:
In a pressure control valve for a fuel injection pump, which includes a piston displaceable in the cylinder by the pressure fluid admitted in the cylinder and against the force of a restoring spring which biases the piston, the piston is closely guided in the cylinder with an annular gap which can be maintained constant. The piston includes one portion which forms the annular gap with the wall of the cylinder and two lateral guide portions closely guided in the cylinder. The annular gap is in communication with the pressure control chamber and the spring chamber formed in the cylinder. A throttle is formed at the discharge of the spring chamber. The amount of fuel flowing through the annular gap builds up a compensation pressure at the throttle to compensate for the influence of temperature fluctuations in the fluid admitted in the pressure control chamber of the cylinder.
