Abstract (en)
Radial piston pump comprises preferably several pump elements arranged radially to a drive shaft positioned in a pump housing (1). The pump elements are operated by the drive shaft and each pump element has an intake side and a high pressure side. The pump housing has high pressure channels (27a-c) which connect the high pressure side of a pump element to a high pressure connection (33). The high pressure channels have very few branches (35, 37). The angle (alpha , beta ) between a high pressure channel and another high pressure channel is approximately 90[deg]. Preferred Features: The high pressure channels are reinforced by tubular inserts (39a-c) made of a strong material, especially high strength steel.
