    摘要: The invention relates to a pressure control valve (10) for controlling the pressure in a high-pressure chamber (3) of a high-pressure accumulator (1), in particular of a high-pressure accumulator for fuel. The pressure control valve (10) comprises a valve body (21), a valve seat (20) formed on the valve body (21) and a closing member (30). The closing member (30) interacts with the valve seat (20) in order to open and close a hydraulic connection from the high-pressure chamber (3) to a low-pressure chamber, wherein the valve body projects at least partially into the high-pressure chamber (3). A recess (40) is formed in the end of the valve body (21) which faces the high-pressure chamber (3). A pressure sensor (50) is arranged in the recess (40), in order to determine the pressure in the high-pressure chamber (3).

    摘要: The invention relates to a pressure regulator for a high-pressure ramp of a system for injecting fuel into an internal combustion engine, comprising a solenoid valve element (10) which receives an electromagnet (40). The electromagnet controls a needle (20) that closes a valve seat (30) which is connected to a high-pressure inlet and opens into a discharge chamber (13), said discharge chamber communicating with a liquid recirculation system (5) by means of outlet openings (14). The rear face (12) of the solenoid valve element (10) receives a coil (40) which controls the opening process of an armature (41) that is rigidly connected to the needle (20) and is subject to a closing return spring (25). The discharge chamber (13) is located on the front face (11) of the solenoid valve element (10) on the axis (XX) of the needle (20), and the discharge chamber surrounds the needle. A cavity (15) passes through the discharge chamber, said cavity receiving an inlet valve element (50), and a bore (51) which opens into the valve seat (30) passes axially through the inlet valve element. The discharge chamber (13) through which the needle (20) passes axially and the outlet openings (14) which are connected to the liquid recirculation system open transversally into a wall (131) in the discharge chamber (13) below the upper part (132) of the chamber. The regulator is characterized in that the regulator comprises an annular expansion (70) of the discharge chamber (13) below the outlet openings (14) along the extension of a conical surface (31), which forms the valve seat (30) and an annular dead volume (70), above the surface (54) of the valve element (50), which forms the base of the discharge chamber (13) and has the valve seat (30) in the center of the valve element.

    摘要: The invention relates to a high-pressure fuel pump (28) for a fuel system (10) for an internal combustion engine, comprising a pressure limiting valve (42) hydraulically arranged between an outlet (36) and an area that is upstream of the outlet (36). The pressure limiting valve (42) has a spring-loaded closing element (58), which is radially held in place by a closing body (62), wherein the closing body (62) has a concave receiving portion (66), in which the locking element (58) is partially accommodated. According to the invention, an opening angle (ß) of a radially outer first area (74) of the receiving portion (66) of the closing body (62) is smaller than an opening angle (α) of an radially inner second area (76) of the receiving portion (66) of the closing body (62), wherein both areas (74, 76) are arranged radially outside of a contact region (78) between closing element (58) and closing body (62).
