Abstract
An hydraulic master cylinder has a cylinder body containing a valve of which a valve element cooperates with a valve seat carried by a piston, the piston performing a working movement, in use, to compress fluid in a pressure chamber of the body. The valve element and valve seat are relatively movable to permit opening and closing of the valve. A first abutment is arranged to set the retracted position of the piston and a second abutment, spaced from the first one in a direction opposite to the working piston movement, serves to hold the valve element in a desired open position when the piston is in its retracted position. The first and second abutments are both formed on a sleeve surrounding the piston.
