摘要： A primary piston component for a master cylinder of a hydraulic brake system includes a primary piston housing and an additional piston component, which is configured to be at least partially movable into a cavity of the primary piston housing. An inner piston body extends through the cavity along a central line of the primary piston component. A braking force applied on a brake actuating element is transferable at least partially on the inner piston body, and further on the primary piston housing. The additional piston component is at least partially movable into the cavity between the inner piston body and the primary piston housing, and a brake booster force is transferable at least partially on the additional piston component, and via the inner piston body on the primary piston housing. A method of operating a hydraulic brake system is also described.

摘要： A cup seal (21) of the invention includes an intermediate lip portion (21d), positioned between an inner lip portion (21b) and an outer lip portion (21c), provided in a base portion (21a). The intermediate lip portion (21d) is configured in such a way that first intermediate lip portions (21d1), communication passages (21d3), second intermediate lip portions (21d2), whose axial direction length is less than that of the first intermediate lip portions (21d1), and the communication passages (21d3), which have no lip portion, are cyclically disposed, in this order, in the peripheral direction. An easy elastic deformation portion of the base portion (21a) which elastically deforms easily is formed by the second intermediate lip portions (21d2) and communication passages (21d3) and, by the easy elastic deformation portion elastically deforming easily when supplying liquid, a flow passage with a larger passage area is formed.

摘要： In a cup seal, the hydraulic pressure in a first hydraulic chamber (6) causes a first seal portion (21e) of an outer lip portion (21c) to closely contact to a bottom wall (20a) of a recessed portion (20) and causes a second seal portion (21f) of a base portion (21a) to closely contact to a rear surface (20b) of the recessed portion (20). A double seal due to the first and second seal portions (21e) and (21f) reliably prevents the leakage of a brake fluid from the first hydraulic chamber (6). If the pressure becomes negative in the first hydraulic chamber (6), the tip portion of the outer lip portion (21c) deflects inward and the outer peripheral end of the base portion (21a) deflects forward. Therefore, the brake fluid in the reservoir flows into the first hydraulic chamber (6) through the gaps among the second and first seal portions (21f), (21e) and the wall surface of the recessed portion (20) to maintain fluid-feeding performance.
摘要翻译：在杯形密封件中，第一液压室（6）中的液压使外唇部（21c）的第一密封部（21e）与凹部（20）的底壁（20a）紧密接触，使得基部（21a）的第二密封部分（21f）与凹部（20）的后表面（20b）紧密接触。由于第一和第二密封部分（21e）和（21f）的双重密封可靠地防止制动流体从第一液压室（6）泄漏。如果第一液压室（6）中的压力变为负值，则外唇部（21c）的前端部向内偏转，并且基部（21a）的外周端向前偏转。因此，储存器中的制动液通过第二密封部（21f），第二密封部（21f）和凹部（20）的壁面之间的间隙流入第一液压室（6），以保持流体供给性能。

摘要： A projection (21b4) provided at a tip portion of an inner lip portion (21b) of a first cup seal (21) comes in contact with a second side wall (20c) of a recessed portion (20) and a large axial force is exerted in the axial direction on a first tapered inner peripheral surface (21b1) of the first cup seal (21) from a rear side tapered surface (4b2) of a primary piston (4). This makes it possible to reliably hold the first cup seal (21) in the axial direction by utilizing the axial force. Therefore, the first cup seal (21) can be suppressed from moving in the axial direction. In particular, the projection (21b4) of the first cup seal (21) comes in contact with a tapered surface (20c′) of the second side wall (20c) to obtain a further increased axial force, and the first cup seal (21) can be held more reliably.
