摘要： A reservoir is disclosed which has a tank made of synthetic resin and incorporated a liquid level sensing device whereby the sensing device has a magnetically actuable switch enclosed in a depending hollow tubular portion of the tank and a float having a magnet which is axially slidable on the tubular portion in order to actuate the switch when the magnet and the switch are in proximity with the tank having both upper and lower shells with the upper shell being formed integrally with the hollow tubular portion and one of the shells being formed integrally with a heat shielding skirt portion which surrounds the tubular portion. The heat shielding portion extends into the interior of the lower shell for shielding the tubular portion against the welding heat during the connection of the upper and lower shells.

摘要： The housing of a motor-driven parking brake apparatus includes a pair of cable reaction-receiving portions for receiving reactions from cables generated due to tensions of the cables, and an axial load-receiving portion for receiving axial load from a screw shaft generated due to the tensions of the cables. These portions, which must be formed to have a large wall thickness, are provided on one side of the housing. This structure reduces the size of the housing. In addition, the axial load-receiving portion is provided between the paired cable reaction-receiving portions. This arrangement further reduces the size of the housing.

摘要： A master cylinder includes a piston received in a cylinder body and formed with piston ports. An annular groove is formed in the inner periphery of the piston in its area where the piston ports are formed. An arcuate plate is received in the annular groove. A sleeve is inserted into the arcuate groove to retain the arcuate plate in the annular groove. A gap as a fluid passage is defined between the arcuate plate and the inner surface of the annular groove. A pressure chamber defined in the cylinder body communicates with a communication passage communicating with a reservoir through the above gap, cutouts of holes formed in the arcuate plate and holes formed in the sleeve. When hydraulic fluid flows rapidly from the pressure chamber toward the reservoir, the arcuate plate is adapted to elastically and radially expand, thus closing some of the piston ports.

摘要： In a vacuum type brake booster, the reaction of output transmitted from an output shaft to a reaction member is transmitted to a valve body, a plunger, and a stepped pin. A valve mechanism, which is assembled to an axial hole of the valve body, includes an atmospheric valve seat which advances and retreats together with the plunger, a vacuum valve seat assembled to the valve body to advance and retreat, and a valve member having an atmospheric valve portion which forms an atmospheric valve in cooperation with the atmospheric valve seat and a vacuum valve portion which forms a vacuum valve in cooperation with the vacuum valve seat. The stepped pin is pushed rearward when a corresponding portion of the rear surface of the reaction member deforms and bulges rearward, and pushes the vacuum valve seat rearward in relation to the valve body.

摘要： A master cylinder includes a cylinder body and primary and secondary pistons slidably received in the cylinder body, thereby defining first and second pressure chambers in the cylinder body. The first and second pressure chambers communicate with a reservoir through first and second fluid passages, respectively. During automatic brake control such as traction control or vehicle stability control, hydraulic fluid is drawn from the reservoir through the first and second pressure chambers. A throttle valve is received in each of the first and second fluid passages. The throttle valves are adapted to open while the master cylinder is inoperative and to close under backflow pressure when hydraulic fluid flows from the pressure chambers toward the reservoir. The throttle valves each include a floating valve body and a valve seat. The valve seat has its radially outer portion liquid-tightly joined and fixed to the cylinder body so that the fixed position of the valve seat and the lowermost position of the floating valve body are determined by the cylinder body.

摘要： A master cylinder includes a primary piston and a secondary piston, each formed with piston ports which include two different kinds of ports, i.e. first ports for ensuring communication between a reservoir and a pressure chamber of the master cylinder, and second ports through which brake fluid is sucked from the reservoir during automatic break control. The second ports are greater in number than the first ports and are positioned forwardly of the first ports so that the second ports are closed by primary cups which are provided on the inner wall of the cylinder body so as to be in sliding contact with the respective pistons before the first ports when the respective pistons are advanced. An annular wall having a greater inner diameter than the outer diameter of the pistons is formed on the inner wall of the cylinder body to support the back of each of the primary cups. An annular groove is formed in each piston so as to communicate with the first ports. The annular groove is preferably arranged so as to radially oppose the annular wall when the piston is in an inoperative position.

摘要： In a negative pressure type booster, an atmospheric valve seat is formed on an annular disk of an input member, which disk extends radially outward. The annular disk and an annular diaphragm located frontward of the annular disk and mounted to the input member define an annular atmospheric chamber. The atmospheric chamber communicates with the atmosphere via an air hole formed in the annular disk. The diaphragm is supported from the front by a power piston. The diaphragm is a flexible member. Inner and outer circumferential portions of the flexible member are formed into respective rolling portions for allowing frontward/rearward movement of the input member by means of curviform deformation. An atmospheric control valve portion, which is seated on and separated from the atmospheric valve seat, and a vacuum control valve portion, which is seated on and separated from a vacuum valve seat formed on the power piston, are axially separated.

摘要： A vacuum servo unit is provided with an actuator for controlling the distance between the engaging portion of a first input member with a reaction disc and an air pressure valve seat in response to a driving force. The vacuum servo unit further includes a rubber member disposed between the first input member and a movable core. The rubber member is deformable in response to the relative movement of the first input member and the movable member forming a part of the actuator. When the actuator is inactive, an axial space is formed between the reaction member and the first input member and between the first input member and a second input member.

摘要： A vacuum brake booster includes a housing provided with at least one pressure chamber, a movable wall dividing the pressure chamber into a front chamber connected to the vacuum source and a rear chamber selectively connected to the front chamber and atmospheric pressure, a power piston connected to the movable wall, an input member disposed in the power piston, and a valve mechanism. An output member outputs the forward movement force of the power piston by moving forwardly with forward movement of the power piston in response to the movement of the movable wall. An auxiliary movable wall is disposed in the front chamber and is movable in the forward and rearward directions. The auxiliary movable wall moves the output member through engagement with the output member. A partition member is disposed in the front chamber and defines an auxiliary chamber in the front chamber with the auxiliary movable wall. The rear chamber and the auxiliary chamber are adapted to be connected with each other.
