A fluid supply system may include a component and a bypass valve including a valve body arranged in a control channel. The valve body may be adjustable at least between a first position and a second position, the valve body cutting off a fluid channel to the component when in the first position and cutting off a bypass channel bypassing the component when in the second position. The valve body may divide the control channel into a first chamber and a second chamber. The valve body may include a leakage opening connecting the first chamber and the second chamber. The system may also include at least one detection device configured to detect a property of a fluid and transmit the detected property to a control device. The control device may be configured to close a switchable valve arranged in the leakage channel when the detected property reaches a predefined condition.
