Hydraulic cylinder, particularly for hydraulic power steering in motor vehicle, has cylindrical shaped housing, which has casing section and discharge opening formed in casing section

摘要

The hydraulic cylinder (10) has a cylindrical shaped housing (12), which has a casing section (14), a piston (18), which is axially moved in the housing and a discharge opening (20) formed in the casing section. The piston, which has an air inclusion collector (28), is pushed over the discharge opening. The air inclusion collector defines an annular channel (30) running in circumferential direction of the casing section.
