    摘要： The invention relates to a primary spring device (100) for a tandem master-cylinder unit, which is to be installed between the primary piston and the secondary piston of the tandem master-cylinder unit. The device (100) includes a plastic frusto-conical abutment (110), the thickness of which is not constant. The thickness of the wall of the body of the abutment at the apex (112) and adjacent to the apex is increased relative to the remainder of the wall. Longitudinal ribs (125) for stiffening and for guiding the head (141) of the screw (140) are provided on the inner surface near the apex and over a certain length of the body. A compression coil spring (150) is supported between the outer abutment collar (115) of the base (114) of the abutment (110) and a bearing disc (144) installed to as to be adjustable by means of a nut (143) at the end of the body (142) of the screw.

    摘要： Master cylinder having a body equipped with a bore housing at least one piston operated by the driver. The piston, which forms a slide valve, separates the feed chamber connected to the brake fluid reservoir from a pressure chamber connected to the brake circuits. The feed chamber is bordered by a groove (152) accommodating a seal (180) separating it from the outside, with respect to the surface of the piston (130). The seal (180) has a cross section in the shape of a lying-down U, one leg (181) of which is pressed against the closed end (152a) of the groove (152) and its two adjacent wall (152b, 152c), the other leg (182) providing sealing by pressing against the piston (130). The end (184) of at least one of the two legs (181, 182) has a flat surface intended to press against the side (152c) of the groove (152).

    摘要： The invention relates to a primary piston (130) consisting of a skirt (132) and an intermediate bottom (131) having a rear surface (131a) receiving the plunger of the brake booster and a front surface (131b) for the telescopic rod and the spring pushing the secondary piston. The front of the skirt (132) comprises longitudinal grooves (137) that are opened at the front (137a) and closed at the back (137b). The body of the skirt (132a) below the grooves (137) and the portion of the skirt between two consecutive grooves (137) in the peripheral direction form a front surface (132S) enabling the main piston to push the secondary piston. The main piston (130) is made in one piece from a plastic material.
