Hydraulic control valve arrangement i.e. fitting cartridge, for performing pressure and volumetric flow control of axial-piston pump, has spring assembly supported at spring seat that stands in threaded engagement with housing-fixed element

摘要

The arrangement has a valve body guided into valve bores (22) that are formed in a valve housing (2). The valve body is pre-tensioned over a spring assembly in a direction, where the spring assembly is supported at a spring seat (26), whose axial position is fixed by an expander. The spring seat or the expander stands in a threaded engagement with a housing-fixed element. The expander comprises a ball, which is pressed into a case hole of a resiliently formed caulking portion, which is arranged at a distance to a threaded section.
