    摘要: To insure that no air bubbles are included in a pump of an anti-locking system, the pump is placed into the master brake conduit, thereby causing it to be scavenged by manual brake operation. Once a brake pressure of about 5 bar is attained, a switch-over valve (28) is switched-over, causing the master brake conduit in the pressure build-up direction to be blocked. Additionally pressure fluid is supplied to the secondary conduit (26) and a pressure opening valve (27). The pressure decrease is effected through the direct conduit (13). In the event of a brake slip control, the pump takes in pressure fluid from the reservoir (25) through the suction valve (22).

    摘要: A slip-controlled brake system is disclosed having a hydraulic power booster and a master cylinder arranged downstream of the power booster, wherein the pressure chamber of the power booster can be acted upon by an external pressure depending on the position of a pedal-actuatable brake valve, and wherein a fast-fill cylinder is provided which can be acted upon by the dynamic pressure and through which additional pressure fluid can be supplied to the brake circuits of the master cylinder. The fast-fill cylinder is equipped with a three-step bore wherein a piston with three shoulders is longitudinally displaceably arranged. A chamber in front of the large drive surface of the piston is connected to the dynamic brake circuit through a pressure fluid line and a chamber in front of an end face of the small step is connected to a static brake circuit through a second pressure fluid line. A first annular chamber formed between the large shoulder of the piston and the medium-sized step of the stepped bore than communicates with a second annular chamber formed between the medium-sized shoulder of the piston and the small step of the stepped bore through a pressure fluid channel and a valve. The second annular chamber is connected to a return line. In the event of a brake pressure control, additional pressure fluid flows from the chamber in front of the small step of the piston of the fast-fill cylinder into the brake circuit through the pressure fluid line. In this case, the fast-fill cylinder operates independently of the functioning of the anti-lock system.

    摘要: There is presented a method for assembling a tandem master cylinder and a vacuum brake power booster of a hydraulic brake system for automotive vehicles. Air is injected via the pressure connections (19, 36) of the pressure chambers (11, 18) associated with the pistons (2, 3). Simultaneously, the pistons (2, 3) are moved in the direction away from the brake pedal. The pressure increase in the pressure chamber (18) is measured during the movement of the pistons (2, 3) and thus during the movement of the central valve (14) accommodated in the floating piston (3). The air pressure in chamber (18) will rise as soon as the closing member (15) of the central valve (14) has moved to sit on the valve seat (16) and the central valve is closed thereby. A trigger point which determines a measured distance on the abscissa of the diagram is fixed in the curve of the diagram "Pressures as a function of the travel of the central valve", the said curve indicating the pressure increase. This measured distance dictates the number and/or dimensioning of spacing washers (8) which are to be arranged between the pressure element (9) and the push rod piston (2) in order to accomplish a reduction of the lost travel of the central valve (14). The present invention serves to accomplish an elegant method in conformity with the demands of automation for assembling a tandem master cylinder and a vacuum brake power booster, as well as a simultaneous reduction of the lost travel of the second central valve (14).

    摘要: A pressure supply system for the generation of the auxiliary pressure of a hydraulic brake system for motor vehicles comprises an accumulator, a hydraulic pump driven by electromotive force and a pressure switch (1) controlling the turning on and off of the hydraulic pump. The pressure switch (1) includes a switch piston (2) having a piston rod (5) mechanically actuating in a pressure-responsive manner, successively, two or three switches (8,9,10). The pump motor (26), by way of these switches, and by way of a relay, is turned on when a bottom pressure limit value (P.sub.U) is reached, and turned off when the upper pressure limit value (P.sub.O) is reached and exceeded. A holding circuit is connected in the electric circuit, in which are provided the switches (8,9,10) of the pressure switch (1), which holding circuit ensures an abrupt switch-over of the relay into the other switching position when a slow approach of a pressure (p) to the pressure limit values (p.sub.U, P.sub.O) causes fluttering of the relay contacts.

    摘要: Dual-circuit brake force control systems are known in which the initial preloading force is changeable dependent on the vehicle load. The initial preloading force is distributed to the control pistons by a lever. Due to manufacturing tolerances and erosion of the individual elements, considerable differences in pressure in both brake circuits may occur. Therefore, according to the instant invention a control lever is provided to directly actuate both control pistons and which is rotatable about an axis perpendicular to the axes of the control pistons and also rotatable about the longitudinal axis of the lever. A holding member shaped like a ball bearing enables the lever to rotate about these two axes. Adjustable stops are provided which cooperate with circular stop surfaces extending from the lever on opposite sides of the longitudinal axis with the center of the stop surfaces being disposed in a plane parallel to the longitudinal axes of the control piston and containing the axes of the control piston.

    摘要: In a pressure control valve for a hydraulic brake system for vehicles, the closure member is carried by a control piston which has one of its ends guided through an annular seal and in a housing bore, which is preferably connected to atmosphere, and carries adjacent its other end a support plate for engagement with a valve spring. The valve seat is part of an annular body encircling the control piston and held in place by a tubular body surrounding the annular body and the control piston and secured to the housing. A return channel is formed between the annular body and the tubular body and incorporates therein a check valve opening in the direction from the outlet chamber to the inlet chamber. The annular seal is in abutment with a step in the housing and the annular body is in abutment with an inner flange of the tubular body. To obtain a minimum possible overall axial length, the annular body and the annular seal are arranged adjacent each other, leaving a clearance for radial channels. An elastic profile ring serves both as a valve seat and as a closure member of the check valve. The profile ring may be formed separate from or integral with the annular seal.

    摘要: A radial piston pump is described with dual pistons which are slidingly accommodated within a bushing coupled end to end to a valve body. Automatically controlled suction and discharge valves for a pressure chamber are arranged one behind the other in the longitudinal axis of the pump. The pistons are sealed by means of elastomeric seals compressed by an end of the valve body and bushing under pressure of a threaded sealing plug installed in the pump housing. The valves, valve body and bushing form a cartridge separately assembled and installed as a unit in the housing. The threaded sealing plug is formed with a damping chamber for damping of pressure pulsations.
