摘要： The invention relates to a high-pressure fuel pump (5) for an injection system of a combustion engine, having a pump housing (16), and a pump piston (14) which is guided in a pump cylinder and can be moved up and down by translation, wherein a temperature sensor (22) is provided for determining the temperature of the fuel conveyed by the high-pressure fuel pump (5). According to the invention, a high-pressure fuel pump (5) having increased robustness is provided. This is achieved by arranging the temperature sensor (22) in the area of the high-pressure fuel pump (5). In particular, the pump piston (14) is moved by a plunger (17) which is guided in a receptacle (13) and delimits an upper plunger space (20) in said receptacle, and the temperature sensor (22) is arranged in the area of the upper plunger space (20) or of a connecting line (21) between two upper plunger spaces (20). The temperature detected by the temperature sensor (22) is preferably used for controlling a low pressure pump (2) and thus for regulating the cooling of the high-pressure fuel pump (5).

摘要： The invention relates to a high pressure fuel pump for a fuel injection system of an internal combustion engine having a pump housing 1, having an interior pump chamber 2 to which fuel is supplied, and having at least one pump element actuated by a pump shaft 3, which is rotatably mounted in the pump housing 1, via a roller plunger 5, which is slide bearing mounted in a guide, forming an upper plunger chamber 9, wherein the interior pump chamber 2 is fluidically connected to the plunger chamber 9. According to the invention, a high pressure fuel pump is provided by which a specific fuel flow of the at least one plunger chamber 9 is ensured. According to the invention, said aim is accomplished in that the plunger chamber 9 is connected to a fuel line 13 effecting a fuel throughput.

摘要： The invention relates to a high pressure pump of a fuel injection system of an internal combustion engine, having a pump housing 1 in which a pump camshaft 2 is rotatably mounted and interacts with a pump piston base 15 of a pump piston 5 by means of a roller tappet 4 disposed in a tappet body 10 and engaged with an inner annular flange 18 of the tappet body 10, said pump piston being displaceable up and down in a pump cylinder 8 disposed in the pump housing 1 and covered by a pump cylinder head 7, forming a pump working chamber 6. A spring disc 16,16a rests on the inner annular flange 18 opposite the roller tappet 4 and encloses the pump piston base 15, and a pump spring 17 is disposed between the spring disc 16,16a and the pump cylinder head 7. According to the invention, noise emission behavior of a generic high pressure pump is improved. Said aim is achieved in that a clearance compensation device is provided for compensating for a clearance between the pump piston base 15, the roller shoe 12, and the spring disc 16,16a.

摘要： The invention relates to a high-pressure fuel pump (1) comprising a drive shaft. According to the invention, fuel flows through the bearings (39) and (41) of the drive shaft (35) in a forced manner in such a way that the mechanical and thermal load-carrying capacity of the bearings, and thus the entire high-pressure fuel pump (1), is significantly increased.
