Abstract (en)
[origin: WO2013075949A1] The invention relates to a high-pressure pump for a fuel injection arrangement of an internal combustion engine. The high-pressure pump (2) has a pump housing (4) with a pump housing interior (6) charged with a fuel (100). At least one pump element having a pump piston (8) is arranged in the pump housing (4). The pump piston (8) is indirectly supported by a plunger body (10) and a roller (12) on a cam (14) or on an eccentric of a drive shaft (16). The plunger body (10) can be driven in an oscillating motion (Z) in the direction of a centre axis (I) via the cam (14) or the eccentric. A roller shoe (18) is firmly connected to the plunger body (10) in the direction of the centre axis (I). The roller shoe (18) has a substantially partially cylindrical recess (20) for partially accommodating the roller (12). According to the invention, the roller shoe (18) has at least one lubrication chamber (22), fuel (100) being fed out of the pump housing interior (6) through the at least one lubricating chamber (22) during the oscillating motion (Z) of the plunger body (10) of the roller (12).
