AFSLUITER VOOR DE AFVOEROPENING VAN EEN RESERVOIR.

摘要

The valve plate (7) is movable along sliding guide rollers (8) within a housing (6) and can be urged vertically against a gasket (4) running around the outlet aperture (A) by means of a cam means (14), which extends substantially over the entire length of the front and/or back edges of the outlet aperture (A). A rod (10) moves the plate between open and closed positions, while a rod (16) through links (15) rotates the cam means.
