    • Described is a bypass-mounted filter assembly, in particular a filter for filtering fluid from a hydraulic-fluid reservoir in a bypass line, the filter having a motor-driven pump and a rigidly mounted housing which is closed off by a cover and which contains a replaceable filter element. The invention proposes that the drive of the pump, the pump and the filter housing are mounted coaxially to each other, the end of the filter housing closed off by the cover facing upwards. The filter housing is connected directly to the pump and forms a vessel designed to hold the clean fluid when the filter element is changed in order to make it possible to replace the filter element or renew the filter simply without any danger of contaminating the clean oil downstream of the filter.

    • The invention concerns a hydraulic circuit designed to supply a consumer with hydraulic fluid, the circuit comprising a hydraulic-fluid reservoir, a first pump which feeds the hydraulic fluid to the consumer and a return filter which filters the fluid returning from the consumer. In order to ensure the supply of fluid, even in the event of pump failure, without the need for a sophisticated design, the invention proposes that the return filter is connected on the upstream side by a line to the hydraulic-fluid reservoir, the line including a pressure-relief valve and a suction valve fitted antiparallel to each other and ending at a point below the level of the hydraulic fluid in the reservoir.

    • The invention concerns a hydraulic circuit with a reservoir which supplies hydraulic fluid via a pump to a consumer, and with a return filter comprising a filter housing containing a filter element for the hydraulic fluid returning along a return line from the consumer. In order to make degassing easier, the invention proposes that a first pressure valve is fitted in the return line before it enters the return filter, the valve not allowing the returning fluid to enter the filter until the pressure has risen above a predetermined first value. Connected to the return line upstream of the first pressure valve is a degassing device leading to the atmosphere and a bypass line containing a second pressure valve and leading to the hydraulic-fluid reservoir. The second pressure valve does not open until the pressure has risen above a predetermined second value and allows fluid to return past the return filter to the reservoir, the second pressure being higher than the first. The degassing device allows gas to flow out to the atmosphere, but prevents hydraulic fluid from escaping.
