ABSTRACT:
A flowing-out passage consists of a small-diameter portion located at the cylinder side and a large-diameter portion located at the orifice side. Provided in the passage is a secondary valve. Skirt-shaped seals are mounted on a secondary valve and set in sliding contact with the inner surface of the flowing-out passage to prevent communication between the small-diameter and large-diameter portions. The secondary valve has a valve spring, a valve body, and a valve seat located at the orifice side. The valve spring set the valve body in contact with the valve seat. Liquid pressures are applied on the secondary valve on both sides. The valve body can be moved away from the valve seat against the force of the valve spring, by a difference between the liquid pressures.
