A VARIABLE ORIFICE IS PROVIDE BETWEEN THE VARYING PRESSURE SUPPLY AND THE PISTON CHAMBER. THE PRESSURE-REDUCING EFFECT OF THE ORIFICE VARIES WITH EXTENSION OF THE PISTON OVER A SUBSTANTIAL PORTION OF THE MOVEMENT OF THE LATTER IN ACCORDANCE WITH THE PRESSURE-TIME CHARACTERISTIC OF THE VARYING SUPPLY IN ORDER TO PROVIDE THE SUBSTANTIALLY CONSTANT PRESSURE IN THE PISTON CHAMBER.
