摘要:
A pressure relief valve suitable for limiting fluid pressure in a common rail of a fuel injection system comprises a first housing part having a first through-bore with a first segment, a second segment and the valve seat defined therebetween. A second housing part is screw fastened with the first housing part and includes a second through-bore disposed coaxially to the first through-bore. An overall rod-shaped valve member is axially displaceable within the second segment. A spring biases the valve member towards the valve seat. A portion of the valve member opposite of the valve seat includes a shaft having a terminal end formed with a non-round cross-section configured such that a tool inserted through the second through-bore and engaging the non-round cross-section prevents the terminal end, and thus the valve member, from rotating relative to the first housing part when the first and second housing parts are screwed together.
