Abstract
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.
