Abstract
The master-cylinder comprises a body defining a cavity therewithin, a bore opening into the cavity, a floating piston slidable in the bore to define a first chamber and a second chamber including the cavity, a spool valve for controlling fluid pressure in the second chamber upon actuation of a control rod, a lever mechanism interconnecting the rod, the piston and the valve for opening the latter, and a cut-off valve located in the first chamber for controlling the fluid flowing out from the first chamber. The cut-off valve includes a valve seat surrounding the outlet port of the first chamber and a valve member secured to a plunger slidable in an inner bore located in the floating piston, the inner bore opening at one end into said first chamber and at the other end into a compartment communicating with a low pressure reservoir and a spring biasing the plunger in abutment with a stop fixed relative to the floating piston.
