Abstract
In a valve arrangement with a first and a second fluid connection (,), a valve element (,) which is biased into a first position by a spring arrangement (,), in which the first and the second fluid connections (,) are blocked from each other, an actuation means (,) in order to bring the valve element (,) into a second position in which the first and the second fluid connections (,) are in a primary flow connection (A), a relatively large flow cross-section between the fluid connections is to be made, on the one hand, the force to be exerted by the actuation means, on the other hand, is to be relatively low in order to save costs, efforts, as well as installation space. For this purpose it is proposed that a further valve element (,) be provided which is biased into a first position by a further spring arrangement (,), in which the first and the second fluid connections (,) are blocked from each other, and which by means a further actuation means can be brought into a second position in which the first and the second fluid connections (,) are in a secondary flow connection (B), are initially in the secondary flow connection (B) only, and subsequently are in the primary flow connection (B) or in the first and the second flow connection (A, B), with the flow cross-section of the primary flow connection (A) being larger than the flow cross-section of the secondary flow connection (B). In a particularly preferred manner, the inventive valve arrangement is utilised in a lock-protected brake system.
