The valve plate (7) is axially displaceable by an operating control (18) fitted in the valve housing (2). The plate also has a locating part (10) movably fitted in a guide casing (12), which is fixed via radial arms (13) in the centre of the housing. - A movable arm (22) engages the locating part with one end (24), and is supported on its own locating part (21) arranged in or connected to the housing. The operating control engages the arm, which as a gearing to the locating part and valve plate, transmits the operating control movement with increased stroke length. |
