摘要： The invention concerns a hydraulic master cylinder comprising mainly a body (1) bored with a hole (100) partially closed by a centring ring (11), a piston (3) mounted sliding in the centring ring (11), a pressure chamber (4) defined in the hole (100) by the piston, an inlet for low pressure hydraulic fluid, and a refill passage (21) for filling the pressure chamber with hydraulic fluid when the piston is inoperative. The invention is characterised in that the refill passage (21) is defined between a flare (104) and the front edge (62) of a ring (6) sliding in the body between the centring ring (11) and the pressure chamber (4) and elastically urged away from the centring ring (11), the piston (3) and the sliding ring (6) having respective stops (31, 61) enabling the piston (3) to drive the sliding ring (6) when it returns to its inoperative position. Said arrangement prevents the piston (3) sealing cup (92) from being damaged, the refill passage (21) thus defined presenting a null length when the sealing cup (92) crosses it.

摘要： The invention relates to a master cylinder (10) for a hydraulic vehicle brake system comprising a housing (12) and pressure piston (16) which is guided in a displaceable manner therein and which delimits a pressure chamber (40) for hydraulic fluid in said housing (12). The pressure piston (16) has a preferably cylindrical recess (48) in the end section thereof which faces the pressure chamber (40). Said recess is fluid-connected to said pressure chamber (40) and is connected to the outer peripheral surface of the pressure piston (16) via at least one compensating bore hole (64'). A throttling element (74, 74') is arranged in the recess (48) of the pressure piston (16) in order to reduce the free travel of the master cylinder (10), said free travel being useless for building up the brake pressure. When the pressure piston (16) is displaced in a direction of pressure build-up, said throttling element throttles the compensating bore hole (64') in order to at least prevent the hydraulic fluid from flowing out of the pressure chamber (40) through said compensating bore hole. The throttling element (74, 74') permits the hydraulic fluid to flow into the pressure chamber (40) through the compensating bore hole (64') in an unrestricted manner when said pressure chamber (40) is relieved from pressure.

摘要： The invention concerns a master cylinder for a hydraulically operated vehicle clutch or brake, with a guide sleeve (5) which is disposed in a housing (2) and in which a piston (6) is guided so as to be axially displaceable. The piston (6), which delimits a pressure chamber (17), is sealed via grooved annular seals, a primary seal (18) and a secondary seal (13). In one end position of the piston (6), a radially inward dynamically stressed sealing lip (22) of the primary seal (18) forms with respect to the piston (6) an annular gap (24) which allows a flow connection from a line connection (3) to the pressure chamber (17). According to the invention, a seal carrier (15), which is mounted axially upstream of the guide sleeve (5) in the direction of the pressure chamber (17) and is inserted in the housing (2), is provided for guiding the piston (6), the primary seal (18) being introduced into this seal carrier (15). In one end position of the piston (6), the sealing lip (22) of the primary seal (18) is axially offset relative to a front face (23) of the piston (6).

摘要： A known hydraulic vehicle brake system (DE 44 45 401 A1) has brake pressure modulation valve systems situated between a dual-circuit main brake cylinder and vehicle wheel brakes. Traction control is ensured by a pump device which is supplied from a reservoir of the main brake cylinder and forces hydraulic fluid into a first pressure chamber between a first piston and a second piston and feeds it to the brake pressure modulation devices connected to said first pressure chamber in order to lead at least a portion of it into the wheel brakes. The pressure in the first pressure chamber displaces the second piston, thereby ensuring that pressure is also applied to the other brake pressure modulation valve devices. The pump device is therefore a high-pressure pump. It is proposed that the pump device should take the form of a low-pressure pump (76), and a first and second return pump (40, 41) should be allocated to the brake pressure modulation valve devices (42, 43, 44, 45); in automatic brake operation, the first pressure chamber (17) should be connected to the first return pump, while the second pressure chamber (18) should be connected on the inlet side to the second return pump. The low-pressure pump (76) generates in automatic brake operation a load pressure for the return pumps (40, 41) significantly lower than a maximum brake pressure, and the return pumps (40, 41) generate the highest predetermined brake pressure and serve in any anti-lock operation to pump hydraulic fluid from the wheel brakes back to the main brake cylinder. Inside the proposed vehicle brake system, the inexpensive low-pressure pump (76) ensures a high level of efficiency of the return pumps (40, 41) in automatic brake operation.

摘要： A piston with a central valve is disclosed, in particular for hydraulic amplifiers. Pistons having a valve insert (6) that consists of a bearing insert (8) radially surrounded by a valve seat (7) are known. The disadvantage of such valve inserts is that the force connection between both elements in the axial direction is not sufficient in some cases. To help solve this problem, the invention provides undercuts, so that the valve seat (7) engages the bearing insert (8) from behind in both directions. In an advantageous development of the invention, the valve insert (6) is symmetrical and a sealing projection is shaped on the valve seat. The guidance of the valve pushrod (19) is provided in the piston (1) itself.

摘要： The proposal is for a brake master cylinder for an anti-lock hydraulic braking system with a central valve (10, 11) in each piston (6, 7). The central valve (10, 11) consists of a first valve (44, 35) and a second valve (40, 37). The first valve (44, 35) opens to a smaller extent A than that B of the second (40, 37). The first valve (44, 35) consists of metallic material whereas the seal of the second (40, 37) is of soft elastic material, e.g. a rubber ring (40). The first valve (44, 35) can assume a pressure regulating function as it is made of hard material. There is nevertheless the risk that particles of dirt in the pressure medium may be deposited in the valve ball (14) or in the seat (35) preventing the valve from closing completely. If this occurs, at least the closing function of the central valve (10, 11) is assumed by the second valve (40, 37). The second valve (40, 37) can also assume a pressure regulating function to a limited extent.
摘要翻译：该建议是用于在每个活塞（6,7）中具有中心阀（10,11）的防抱死液压制动系统的制动主缸。中心阀（10,11）由第一阀（44,35）和第二阀（40,37）组成。第一阀门（44,45）比第二阀门（40,37）的B开度小。第一阀门（44,35）由金属材料组成，而第二阀门（40,37）的密封件是柔软的弹性材料，例如，橡胶环（40）。第一阀（44,35）可以承受由硬质材料制成的压力调节功能。然而存在压力介质中的污垢颗粒可能沉积在阀球（14）或座（35）中的风险，防止阀完全关闭。如果发生这种情况，则第二阀（40,37）至少假设中心阀（10,11）的关闭功能。第二阀（40,37）也可以在有限的程度上承担压力调节功能。
