Abstract
Official abstract text for this publication.
A hydraulic valve arrangement, in particular a control valve arrangement, of a hydraulic machine, in particular a hydraulic pump, includes at least one valve with a valve body penetrated by a pressure medium passage. The pressure medium passage has a minimum cross section that gives rise, in normal operation, to a control pressure downstream of the minimum cross section in accordance with a pressure acting at a pressure port of the valve. The minimum cross section is arranged close to a pressure medium passage mouth which is arranged upstream or is configured to be subjected to the high pressure. A hydraulic machine arrangement, in particular a pump arrangement, includes the hydraulic valve arrangement.
First claim
Opening claim text (preview).
What is claimed is: 1. A hydraulic valve arrangement, comprising: a first valve including: a pressure port having a high pressure; and a valve body movable in a valve bore and defining a pressure medium passage having a first channel portion extending axially along the valve body and a second channel portion extending radially from the first channel portion to an outer surface of the valve body, the second channel portion including a first end at the outer surface, the second c…
