摘要： A brake booster and a method of assembling an output member thereof within a bore of a valve body. In this brake booster, a reaction disc engages a holder of a reaction transmitting assembly which is connected to a plunger of an input member. A guide is attached to a cylindrical head on a shaft of an output member by hooks on the end of a first plurality of legs that extend in a first direction from a cylindrical base. A second plurality of axial legs that extend from the cylindrical base in a second direction are connected to a support ring. The cylindrical base is located in the bore by the support ring being positioned on a shoulder in the valve body by a return spring such that a series of arcuate tabs on the cylindrical base urge a reaction disc retained by the cylindrical head into engagement with the holder.

摘要： A brake booster (12) having a housing (14,16) with a control valve (70) located in an axial bore (54) of a hub (50) carried by a movable wall (22,24). The movable wall (22,24) separates the interior of the housing into a first chamber (26,26′) and a second chamber (28,28′). The control valve (70) in a first mode communicates the first chamber (26,26′) with the second chamber (28,28′) to provide for equal pressures therein and in a second mode communicates the second chamber (28,28′) with a surrounding environment to create a pressure differential across the movable wall (22,24). A reaction member (96) carried by the movable wall (22,24) communicates an operational force created by the pressure differential into an output push rod (94). After the operational force overcomes a return spring (130,130′), the output push rod (94) moves pistons (200) in a master cylinder (202) to correspondingly pressurize fluid therein which is supplied to wheel brakes to effect a brake application. The brake booster (12) is characterized by a retainer (100) having a base (102) with an axial opening (104) and a plurality of axial legs (106,106′ . . . 106n) which extend from the base (102). With the base (102) located in the axial bore (54) a shaft (91) of the output push rod (94) passes through the axial opening (104) while the plurality of axial legs (106,106′ . . . 106n) are located in corresponding a plurality of arcuate and axial slots (82,82′ . . . 82n) in the hub (50) located on the peripheral surface of the axial bore (54). The plurality of axial legs (106,106′) frictionally engage the hub (50) to position the base (102) in the axial bore (54) such that the head (92) of the output push rod (94) is positioned adjacent the reaction member (94) and the shaft (91) is located along the axis of the axial bore (54).

摘要： A brake system has a brake booster secured to a dash panel which separates an engine compartment from a passenger compartment of a vehicle. A bracket off-sets the booster into the engine compartment from the dash panel. A cylindrical body has a flange on a first end located between the housing of the brake booster and the bracket. The cylindrical body has a partition wall located between the first end and a second end and a radial opening located between the partition wall and the second end. The partition wall has a central opening through which an input rod extends to provide a valve with an input force. An end boot, secured to the second end of the cylindrical body and the input rod, forms a resonant chamber within the cylindrical body. The radial opening provides unrestricted communication air from the engine compartment to the resonant chamber while the central opening forms an orifice to control the air flow from the resonant chamber into the valve body. The resonant chamber is of sufficient size to dissipate audible sounds produced by the flow of air through the orifice to the valve.

摘要： A brake booster (12) having a housing (14,16) with a control valve (70) located in an axial bore (54) of a hub (50) carried by a movable wall (22,24). The movable wall (22,24) separates the interior of the housing into a first chamber (26,26′) and a second chamber (28,28′). The control valve (70) in a first mode communicates the first chamber (26,26′) with the second chamber (28,28′) to provide for equal pressures therein and in a second mode communicates the second chamber (28,28′) with a surrounding environment to create a pressure differential across the movable wall (22,24). A reaction member (96) carried by the movable wall (22,24) communicates an operational force created by the pressure differential into an output push rod (94). After the operational force overcomes a return spring arrangement (129), the output push rod (94) moves pistons (200) in a master cylinder (202) to correspondingly pressurize fluid therein which is supplied to wheel brakes to effect a brake application. The brake booster (12) is characterized by the return spring arrangement (129) having a first spring (130) with a right hand spiral and a second spring (130′) having a left hand spiral. The first spring (130) is secured to a base (102) of a retainer (100) and to an end cap (136) to hold the second spring (130′) in a concentric relationship between the end cap (136) and base (102). A housing (202) of a master cylinder (200) engages the end cap (136) to compress the return spring arrangement (129) to an installation height such that the movable wall (22,24) is located in a ready rest position.
