Abstract
A sudden change in the repulsive force of a piston rod and the resulting excessive increase of the vehicular height are to be suppressed. A small-diameter portion 10A and a large-diameter portion 10B are formed in the inner periphery of a pump cylinder 10, and a valve cover 21 is provided at the lower end of a pump rod 9 so as to accommodate an inlet valve 6 therein. The valve cover 21 has a discharge port 6a which when positioned within the small-diameter portion 10A is closed and which when positioned within the large-diameter portion 10B is opened to a pump chamber 12.
