Abstract: A spray gun for fluid, including a body defining an internal pipe, a shutoff member which is movable between a release position and a shutoff position of the internal pipe, a connecting member rigidly connected to the shutoff member, a coupling member having an engaged configuration in which it is fixed relative to the body, and a trigger pivotably mounted about a primary axis relative to the connecting member and about a secondary axis relative to the coupling member, the primary and secondary axes being parallel. The coupling member has a deployed configuration in which it is mobile in translation relative to the body in a direction orthogonal to the primary and secondary axes.

Abstract: A closure device including a closure element for closing an opening surrounded by a valve seat of the closure device. The closure device has an open state, in which the closure element exposes the opening at least partly, for an object to be led through the opening, an intermediate state, in which the closure element is brought into alignment with the opening without contact with the valve seat, and a closed state, in which the closure element at least rests on the valve seat via a seal of the closure device. The seal has a hollow space, to which a pressure medium from a pressure source of the closure device can be applied, and the closure device has a suction apparatus for sucking the pressure medium out of the hollow space of the seal.

Abstract: A closure device (1) including a closure element (2) for closing an opening (5, 6) of the closure device (1) that is surrounded by a valve seat (3, 4) of the closure device (1), wherein the closure device (1) has an open state of the closure element (2), in which the closure element (2) exposes the opening (5, 6) at least partly, in particular completely, for an object to be led through the opening (5, 6), and an intermediate state of the closure element (2), in which the closure element (2) is brought into alignment with the opening (5, 6) without contact with the valve seat (3, 4), and a closed state of the closure element (2), in which the closure element (2) at least rests on the valve seat (3, 4) via a seal (7, 8) of the closure device (1), wherein the seal (7, 8) has a hollow space (9), to which a pressure medium from a pressure source (10) of the closure device (1) can be applied, wherein the closure device (1) has a suction apparatus (11) for sucking the pressure medium out of the hollow space (9) of

Abstract: A vacuum valve including a closure element (3) and a valve housing (1) with a valve opening (4) and an interior (2) in which the closure element (3) is arranged, the closure element resting against a valve seat (6) surrounding the valve opening (4) in the closed state of the vacuum valve. The valve housing (1) has a housing wall (19) made of sheet metal, the housing wall delimiting the interior (2) and being provided with a window opening (20) in order to form the valve opening (4). The valve opening (4) is surrounded by a flange ring (21) that can be connected to a connection flange (28) of a vacuum unit (27) via screw connections, the vacuum unit having an interior and being attachable to the vacuum valve. The flange ring (21) has the valve seat (6) on which the closure element (3) is placed in the closed state of the vacuum valve.

Abstract: A valve (1), in particular a vacuum valve, comprising a valve plate (2) for closing an opening (3), in particular of the valve (1), and comprising at least two piston cylinder units (4, 5) for pressing the valve plate (2) against a valve seat (6), in particular of the valve (1), said valve seat surrounding the opening (3), at least one of the piston cylinder units (5) having at least one cylinder (7) as a component and at least one piston (8) arranged displaceably in the cylinder (7) as a further component, one of the components of the piston cylinder unit (5) being fixed on the valve plate (2), in particular in a manner stationary relative to the valve plate (2), wherein at least one of the components, preferably the other component, of this piston cylinder unit (5) is mounted on at least one support (10, 11) of the valve (1) so as to be movable, preferably displaceable, at least in a direction (9) parallel to the spacing between two adjacent piston cylinders units (4, 5).
