Abstract: In a valve assembly (1) comprising a valve housing (2), a valve seat (3) and a valve body (4) adapted to fit in closing relationship in said valve seat (3) in a closed position, said housing (2) has an inlet (5) and an outlet (6) for a pressurized fluid, positioned upstream and downstream of the valve members, respectively. The valve has a closed position being maintained by a closing force e.g. from a compression spring (7) and an open position, wherein the valve seat (3) and/or the valve body (4) are moved away from each other by an activating mechanism. A pressure balancing line (11) is provided internally or externally of the housing (2), wherein fluid of the fluid flow downstream of the moveable valve member (3, 4) is in fluid connection with the opposite end of said member, when in use.

Abstract: Spraying installation (1) on a chassis (2) of a truck (3), comprising a spraying nozzle (4) at the free end of a telescopic arm (5) attached to the chassis (2) via elevation means, characterized by the telescopic arm (5) being supported in a first position (A) oriented along the length of the truck (3) and above the top of the truck, wherein the telescopic arm (5) is stowed in a horizontal transport position, and supported in at least one other, active position (B, C), whereby the telescopic arm stays in a horizontal position during the movement between said positions (A and B, C) in a space confined between the vertical planes of the two sides of the truck.
