摘要： Maintenance-friendly, compact valve having a simple design for essentially gastight closing of a flow path (F) between two ports (3, 5) arranged at an angle. A valve part which is arranged in a valve housing (2) so as to be displaceable along an axis (10) and whose closing surface (13) can be brought into contact with a valve seat (7) of the first port (3) for closing the flow path (F) and can be brought out of contact for opening the flow path (F) is in the form of a cylindrical piston (9) having an end face forming the closing surface (13) and a piston outer surface (16). The valve housing (2) has a cylindrical passage (17) which extends opposite the valve seat (7) along the axis (10) and through which the piston (9) is passed and can be displaced and inside which a sealing or guide element (15, 18; 19) is arranged. The piston (9) and the passage (17) are dimensioned so that the piston outer surface (16) is closely enclosed along the adjustment distance (a) by the sealing or guide element (15, 18; 19) of the passage (17). It is thus possible for essentially only a single adjustable component of the valve, namely the easily cleanable piston (9) consisting in particular of a single material, to be guided in the flow space (R) so that the maintenance of the valve (1) is substantially simplified and few different materials bound the flow space (R). In a further development, the drive mechanism (14) of the piston (9) is formed at least partly by an outer piston space (A) between a piston step (21) and the passage (17), so that the piston (9) forms a component of the drive mechanism (14), permitting a compact design of the valve (1).

摘要： A vacuum valve comprises a valve body (1) with an inner cavity (4) through which a main passageway leads between an inlet (2) and an outlet (3) of the vacuum valve and with a main valve seat (6) which surrounds the main passageway, a main closing member (5) which is adjustable in the inner cavity (4) of the valve body between an open position, in which it is lifted from the main valve seat (6) and in which the main passageway through the vacuum valve is open, and a closed position, in which it tightly contacts the main valve seat (6) and in which the main passageway through the vacuum valve is closed, and which has an inner cavity (10) through which an additional passageway leads and an additional valve seat (14) surrounding the additional passageway, an additional closing member (11) which is adjustable in the inner cavity (10) of the main closing member (5) between an open position, in which it is lifted from the additional valve seat (14) and in which the additional passageway through the vacuum valve is open, and a closed position in which it tightly contacts the additional valve seat (14) and in which the additional passageway through the vacuum valve is closed, wherein the additional passageway runs through a changeable intermediate space (43) between the main closing member (5) and the additional closing member (11), and the size of this intermediate space (43) is changeable by means of a rotation of the additional closing member (11) relative to the main closing member (5).
