ABSTRACT:
A valve arrangement, comprising a first and a second fluid connection (16, 20) of respective, predetermined flow cross-sections, at least one valve element (44) which is biased by a first spring arrangement (106) in a first position in which the first and second fluid connection (16, 20) are communicating via a flow path, and a valve actuating means (42) by means of which the valve element (44) can be moved in order to assume a second position in which the first and second fluid connection (20) are closed against each other, is characterized in that the bias of the first spring arrangement (106), the force that can be applied to the valve element (44) by the valve actuating means (42), and the flow cross-sections of the fluid connections (16, 20) are dimensioned in such a manner that with a predetermined fluid pressure at the second fluid connection (20), the valve element (44) opens the second fluid connection (20) to such an extent that a flow path is obtained to the first fluid connection (16).
