Title: FLUID SUPPLY SYSTEM
Abstract:
The invention relates to a fluid supply system (1). According to the invention, the following are provided: – a first bypass valve (7) which is arranged in a control channel (6) with a valve body (8) which is adjustable between a first and a second position, – wherein the valve body (8) separates the control channel (6) into a first and a second space (10, 11) and has a leakage opening (12) which connects the first space (10) to the second space (11), – wherein the second space (11) is connected to a fluid reservoir (9) via a leakage channel (14), – wherein a switchable valve (15) for at least partially opening/closing the leakage channel (14) is arranged in the leakage channel (14), – wherein a sensing device (16) and a controlling device (18) are provided, said controlling device closing the valve (15) when a predefined property is reached and therefore blocking the leakage channel (14), – a second bypass valve (26) which is designed in such a manner that a transient oscillation of the first bypass valve (7) during starting of the system is at least reduced.
