Abstract

See full text

Hydraulic system with a hydraulic machine, in particular an axial piston or radial piston unit, with rotating and moving machine components which are arranged in a housing. The housing is connected to a high-pressure and a low-pressure line of a working circuit, which is supplied with pressure fluid by means of a charge pump. The leakage fluid which occurs in the housing collects in a leakage fluid reservoir which is arranged below the rotating and moving hydraulic machine components in the working position of the hydraulic machine and is connected fluidically to the housing. The leakage fluid is pumped out of the leakage fluid reservoir into the low-pressure line of the working circuit by the charge pump.
