Abstract: An axial valve has a housing, an inlet, an outlet, a valve seat between the inlet and the outlet, and a valve element cooperating with the valve seat, and is controlled by a pilot valve arranged between the inlet and the outlet, with the valve element being moveable parallel to a flow path from the inlet to the outlet and surrounding an interior space. Without changing the external measurements of the valve an increased through flow is achieved in that a first section of the flow path leads through the interior space and a pressure space is arranged between the housing and the valve element, in which pressure space in the closed condition of the pilot valve a closing pressure is formed and applied to the valve element.

Abstract: A valve arrangement for use in vacuum systems has a housing (1) with an input opening (3) and output opening (5), between which is arranged a main valve (7) with a closure member (9) biased by a first spring (11) and an auxiliary valve (15) acutable by a electromagnet (18) and having a smaller nominal width than that of the main valve (7). To simplify the valve arrangement and to be able to actuate with less energy, the closure member (9) of the main valve (7) is biased in the opening direction by a first spring (11) and the force of the first spring (11) is larger than a predetermined closing force exerted on the closure member (9) of the main valve (7) by the pressure difference between the input and output openings (3, 5) when the auxiliary valve (15) is open.
