Abstract (en)
[origin: WO2009115353A1] A high-pressure pump (1) is used especially as a fuel pump for fuel injection systems in air-compressing, self-igniting internal combustion engines. Said high-pressure pump (1) comprises a first pump subassembly (17), a second pump subassembly (18), and a drive shaft (3). The first pump subassembly (17) is located at least approximately across from the second pump subassembly (18) in relation to the drive shaft (3). At least one cam (9) for driving both the first pump subassembly (17) and the second pump subassembly (18) is provided on the drive shaft (3). Furthermore, spring elements (40, 41) are provided which are connected to a piston (23) of the first pump subassembly (17) by means of a retaining brace (45) and are connected to a piston (23) of the second pump subassembly (18). The spring elements (40, 41) are mounted in a biased manner such that the two pistons (23, 23) return without separate return springs or retracting springs during operation of the high-pressure pump (1).
