Piston pump for hydraulic brake slip control system, has carrying body provided with profiling in region of channel in such manner that cross-section of channel is section-wise extended in radial direction to inner wall of valve borehole

摘要

The pump (1) has two axially valve units (A, E) arranged in distance to each other and including a valve body (38) and valve springs (41, 42). The valve springs are designed as a cartridge-like valve component that comprises a carrying body (34) and a pressurizing medium passage channel (C). The valve springs are inserted into a valve borehole (17). The carrying body is provided with a profiling in a region of the channel in such a manner that a cross-section of the channel is section-wise extended in a radial direction to an inner wall of the valve borehole.
