Abstract (en)
[origin: EP1067295A2] The system delivers a part of the pressurised fluid from the pump (7) directly to the consumer (8) below a previously defined temperature, independently of a pressure level in front of the filter unit. Above a determined pressure level, the supplied fluid is delivered through the filter unit to the consumer. Above a previously defined pressure, a part of the pressurised fluid is directly supplied from the pump to the consumer.
