摘要： The present disclosure refers to a wear resistant insert element configured to be inserted into a shaft of a baffle body for a plunger operated fuel pump and a corresponding baffle body. Baffle bodies in plunger operated fuel pumps serve for absorbing the energy of a pressure wave generated during pumping operation of the fuel pump. However, conventional baffle bodies made of steel may be subjected to wear, in particular, in case they are used in a fuel pump operated with alternative fuels or low sulfur fuels having a low boiling point and/or a high content of water. The present disclosure suggests a wear resistant insert element possibly made of ceramic and to be inserted into a baffle body such that the end surface of the baffle body is configured to absorb the energy of the fuel pressure wave and, thus, resists wear.
摘要翻译：本公开涉及一种耐磨插入件，其构造成插入用于柱塞操作的燃料泵的挡板体的轴中以及相应的挡板本体。柱塞操作的燃料泵中的挡板体用于吸收在燃料泵的泵送操作期间产生的压力波的能量。然而，由钢制成的传统的挡板体可能受到磨损，特别是在用于具有低沸点和/或高含量水的替代燃料或低硫燃料的燃料泵中的情况下。本公开内容提出了可能由陶瓷制成的并且被插入到挡板体中的耐磨插入件，使得挡板体的端面被构造成吸收燃料压力波的能量，并因此抵抗磨损。

摘要： This invention concerns a fuel injection system for diesel motors consisting of a housing (1), a piston pump (5) which can be controlled, and an injection nozzle (4) connected to it which has a nozzle chamber (25). The housing (1) has a fuel supply chamber (23) fed from without and a return port (24) leading out. The piston pump (5) has a piston liner (6) with control apertures (17) guided by a tappet (20) fixed to the housing. The tappet (20) contains a first longitudinal bore (39) leading from the inside (18) of the piston liner (6) to the injection nozzle (4). To improve the seal and the through flow, the piston liner (6) is surrounded by a sealing sleeve (50) which forms with the outer wall of the liner (6) a closed sealed chamber (53). The tappet (20) has a second longitudinal bore (57) which stands in flow connection on one side with the fuel supply chamber (23) and on the other side with the sealed chamber (53) by means of a first cross bore (54). The sealed chamber (53) stands in flow connection with the return port (24) by means of a second cross bore (58) and a third longitudinal bore (59) in the tappet (20).

摘要： Described is a fuel injection device, in particular a pump injector, for internal combustion engines, in which the start and end of fuel delivery is controlled by a solenoid valve (2) fitted between a low-pressure line and the working space (10) of the pump piston (1). The device has a flush bore (6) in a flush line (7) which can be connected to the working space (10), the flush line being connected to a low-pressure space and the fuel tank. A feed line (3) supplying fuel from the solenoid valve (2) to the working space (10) of the piston (1) opens out directly in the pump working space (10), the connection to this space remaining permanently open. The design is such that the mouth of the flush bore (6) is in the zone of the pump cylinder (4) which is swept by the pump piston (1) in all positions of the piston, and the mouth of the flush bore can be connected in the region of the top dead centre of the piston (1) via a recess, in particular an annular groove (8), in the piston (1) at least directly with the feed line (3) and the working space (10) of the piston (1).

摘要： A fuel injection pump (14) has a barrel (22) with a central bore (23) communicating through axially staggered fuel inlet and outlet ports (66, 64) with an outer peripheral recess (56) in the barrel which, in cooperation with a fuel pump housing (16), forms an annular fuel receiving cavity (58) about the pump barrel. A relatively large fuel reservoir (50) in the housing communicates with the annular cavity (58) through fuel inlet and outlet conduits (66, 64) in the housing (16), the outlet conduit (64) being aligned with the outlet port (60) in the pump barrel. A plunger (24) having a scroll surface atone end is rotatably and reciprocably received in the pump barrel bore (23), and the scroll surface is selectively registrable with the fuel ports (60, 62). A pulse shield (93) of hardened material is disposed within the fuel reservoir (50) in alignment with the fuel outlet conduit (64) to deflect fuel from the outlet conduit into the main portion of the reservoir and to prevent erosion of the housing surfaces.
