    摘要: Dual circuit pressure control valves for brake system are known in which the control pistons are located parallel to each other with each control piston controlling a different one of two brake circuits. Both control pistons are loaded by a common preloading force. The known arrangement is complicated in its construction and has a large overall length. According to the present invention, the construction is simplified and the overall length is reduced by providing a torsion spring which provides the preloading force acting on the control pistons via stationarily supported swivelling levers.

    摘要: In a known dual-circuit braking pressure control valve, a tilting lever arrangement is provided for distribution of the preloading force to the two control pistons, whereby the change-over point of the intact brake circuit is increased upon failure of one brake circuit. The tilting lever arrangement is complicated with respect to its construction and assembly, and its mode of operation is not safe. According to the present invention the tilting lever arrangement is replaced by a carrier bridge at the ends of the two pistons which synchronizes the points of application of the preloading forces by allowing a slight relative movement betweeen the two pistons when both of the brake circuits are operative.

    摘要: Dual-circuit pressure control valves are known in which the control pistons are acted upon by a common control force. A preload distributor constructed as beams of balance to compensate for differences in the control behavior of the two control valves due to manufacturing tolerances have not provided the desired compensation. Therefore, according to the present invention an improved compensation arrangement is provided in the form of a compensating piston which is subjected to the outlet pressures of the two brake circuits.

    摘要: A connecting arrangement for connecting two hollow components of a hydraulic circuit to one another, especially a pipe or hose to a mating component, includes a guiding formation on one of the components, especially the mating component, and a mounting formation connected to the other component, these formations having correlated cross-sectional shapes such that the guiding formation guides the mounting formation in a predetermined direction, especially the longitudinal direction of the one component, and prevents relative displacement in all other directions. The mounting formation is advantageously constituted by a separate mounting element which is affixed to the other component by a threaded connection, such as by a screw cap. The formations advantageously have complementary dovetail-shaped cross-sectional configurations. The formations have respective passages which register with one another in the assembled position of the components and which are surrounded by a seal arranged in the interface between the components.

    摘要: A pressure reducer for hydraulic brake systems comprises a stepped piston carrying a sealing ring in a circumferential groove thereof. The sealing section of the sealing ring begins at the groove wall adjacent the outlet chamber and joins a transitional section of smaller diameter adjacent the inlet chamber. The sealing ring fills the groove essentially completely at least in the sealing section. Preferably the sealing ring abuts the bottom of the groove over its entire axial length. This results in a defined position for the sealing section without excessive friction and wear occurring during operation.

    摘要: Dual-circuit pressure control valves are known in which the two control pistons are acted upon by a common preloading force through the intermediary of a preload distributor. The disadvantage of the known devices is that the valve closure travel is great resulting in a large fluid volume input to the control valve. According to the present invention this disadvantage is overcome by providing adjustable stops which cooperate with corresponding extensions of the distributor as soon as an unsymmetrical mode of operation of the valves occurs.

    摘要: The braking pressure control unit for a dual circuit brake system comprises a housing with two closure members arranged therein coaxially and in tandem. In their rest position, the closure members are held spaced apart from associated valve seats by a control force. The control force acts directly on a first of the two closure members which in turn bears against a second of the two closure members provided both are in the open positions. At least one closure member consists of a shaft element having one end in an operative relationship with the adjacent end of the other closure member and a closure element in a slidably sealed relationship with the outer surface of the shaft element, the closure element being displaced between limits of the shaft element. A weak closure spring biases the closure element toward its associated valve seat.

    摘要: In the process, a spring device is pivotally connected to a transmission lever which is movable between two defined positions. The free end of the spring device is subjected to a defined load and is fixed stationary while the transmission lever is in the defined position corresponding to the closing position of the valve. Thereupon, the length of the prestressed spring device is fixed, which results after swiveling of the transmission lever into the other defined position. The effect of the spring tolerances on the precision of adjustment of the change-over point is excluded. The brake pressure control unit apparatus is provided with first and second stop elements fastened to the spring device with a removable spacing element inserted between the stop elements. The distance between the stop elements corresponds to a determined amount of spring preload fixed by the spacing element.

    摘要: Dual circuit brake force control units are known in which the initial preloading force is changeable dependent on the vehicle load. The preloading force is distributed to the control pistons by means of a lever. Due to the tolerances and erosion of the individual elements, considerable differences in pressure in both brake circuits may occur. Therefore, according to the present invention a lever is provided which directly acts on both control pistons and which is rotatable around an axis parallel to the direction of displacement of the control pistons and additionally around the longitudinal axis of the lever. The lever is in interaction with its housing mount at one support point at least and at two support points at the most with the support point or support points being located at least approximately in the longitudinal axis of the lever.

    摘要: In a dual-circuit pressure control valve for hydraulic brake systems, the control pistons disposed parallel to one another are each loaded by a first arm of an associated angular lever. Each of the levers have a second arm perpendicular to the first arm acted upon by a common tension spring disposed therebetween. The levers are located approximately in a plane defined by the axes of the control pistons. The tilting axes of the levers are disposed perpendicular to this plane and are disposed outside the axes of the control pistons. This results in a short overall length in both the axial and radial direction. In addition, a carrier device is provided which couples one of the control pistons with the lever of the other control piston after a small relative movement of the control pistons. This carrier device becomes effective upon failure of one brake circuit. The carrier device may be formed by extensions of the first arms which overlap one another with play.
