摘要： The invention relates to a radial piston pump (1) for generating high fuel pressure in fuel injection systems of internal combustion engines, especially in a common rail injection system. Said radial piston pump (1) comprises a drive shaft (4) that is mounted within a pump housing (2) and is provided with an eccentric section (6) on which a roller (8) is mounted, and preferably several pistons (16). Said pistons (16) are disposed in one respective cylinder (14) so as to extend in a radial direction relative to the drive shaft (4). A piston base plate (18) that contacts the circumferential surface (10, 12) of the roller (8) is arranged at the end of each piston (16), which faces the roller (8). According to the invention, at least one portion of the roller (8), particularly at least part of the circumferential surface (10, 12) of the roller (8), is made of a wear-resistant material, i.e. hard metal, a precision casting material, cast carbide material, sintered tool steel, or nitrided steel.

摘要： The invention relates to a radial piston pump (1) for generating high pressure in fuel injection systems of combustion engines, particularly in a common rail injection system, comprising a drive shaft (4), which is mounted in a pump case (2), has an eccentric shaft section (6), on which a roller (8) is mounted, and which preferably has a number of pistons (16). These pistons are placed in a respective cylinder (14) while being arranged radial to the drive shaft (4), and a piston foot plate (18) is placed at the ends of the piston facing the roller (8) while being in contact with the peripheral surface (10, 12) of the roller (8). The invention provides that at least the surface (28) of the piston foot plate (18) that contacts the peripheral surface (10, 12) of the roller (8) is made of a wear-resistant material, namely of hard metal, a ceramic material, a cast carbidic material or of cermet, and/or that at least one portion of the roller (8), particularly at least one portion of the peripheral surface (10, 12) of the roller (8), is made of a wear-resistant material, namely of hard metal, a precision cast material, a cast carbidic material, a sintered tool steel or of an alloyed nitrided steel and/or that the piston (16) is made of a ceramic material.

摘要： The invention relates to a radial piston pump (1) for providing fuel high pressure in fuel injection systems of internal combustion engines, especially in a common-rail-injection system. Said radial piston pump comprises a drive shaft (4) mounted in a pump housing (2) with an eccentric shaft section (6) whereon a roller (8) is mounted, comprising, preferably, several pistons (16) which are arranged in a radial manner in a cylinder (14) in relation to the drive shaft (4). A piston bearing plate (18) is arranged on the ends thereof oriented towards the roller (8), said piston bearing plate entering into contact with the peripheral surface (10, 12) of the roller (8). The invention is characterised in that at least the surface (28) of the piston bearing plate (18) which enters into contact with the peripheral surface (10, 12) of the roller (8) is made of a wear-resistant material, i.e., hard metal, of a ceramic material, of a cast carbide material or cermet.
