摘要： A master cylinder having a body with a bore therein delimited by a piston into a work chamber and a supply chamber. The work chamber (16) is connected to wheel brakes, while the supply chamber is connected to a fluid supply, through a supply duct. The piston has a shank retained by a guide ring mounted in the bore and a head bears against a thrust ring in a rest position. A first end of the supply duct is connected to the fluid supply, while a end is connected to the supply chamber. A hydraulic damping arrangement that dampens movement of the piston toward the thrust ring and includes structure for shutting off the second end of the supply duct such that brake fluid flows at a reduced flow rate from the supply chamber to the supply duct through at least one exhaust duct.

摘要： In a process for manufacturing a master cylinder (23) wherein a piston (9) that carries a valve (37) is assembled within a cylinder to define a chamber (41). The piston (9) moving in the chamber (9) in such a way that initial forward travel in cylinder defines a dead stroke as the valve (37) moves from an opened position to a closed position and with further forward travel with the valve (37) in the closed position defines a useful stroke wherein a lessening of an inner volume of the chamber (41) occurs as fluid is pressurized to effect a brake application, characterized in that the process further comprises the steps of: a) installing a first adjusting part (51,55,57) between the valve (37) and piston (9); b) measuring the dead stroke; c) determining from the measurment of the dead stroke an effect that the geometry of the first adjusting part (51,55,57) has on the closure of the valve (37) during the initial forward travel of said piston (9); d) comparing the measured dead stroke with a desired dead stroke for a master cylinder (23); and e) replacing the first adjusting part (51,55,57) with a second adjusting part (51,55,57) to modify the closure of the valve (37) and alter said dead stroke when the measured dead stroke exceeds a predetermined value such thah the resulting dead stroke matches the desired dead stroke.

摘要： The planar abutment key (11) incorporates in its body portion (18) two flexible fingers (22) extending laterally and angularly in the direction away from the end portion (19) of the key which forms abutment arms (21) for the plunger, each finger (22) ending in a sharp angle (24), the transverse distance at rest between the sharp angles (24) being greater than the transverse width (d.sub.1) of the slot (12) in the hub portion of the assistance piston (1) in which the key (11) is housed.
