ABSTRACT:
A diaphragm-actuated slide valve where spring force is utilized to urge the moving slide valve element against the stationary valve element. To obtain a good seal at the valving ports with a minimum of spring force, the moving slide valve element is made to present a convex contact face to the stationary valve element at the port region of the moving valve element. At the same time, a clamping connection of the fluid tube to the moving slide valve element is obtained. The moving slide valve element is in the form of an apertured, initially flat block. The fluid tube passes through an aperture in an initially curved spring clamp plate provided with clamping serrations in the tube-receiving aperture, the tube engaging in a counterbore in the valve block at its port. Clamping screws engage through opposite parts of the clamp plate and threadedly engage the valve block at opposite spaced locations relative to the tube. Tightening the screws clamps the tube in the counterbore and causes the valve block to generate a convex contact face, while straightening the spring plate, because the tube acts as a center abutment for the valve block, loading the valve block in the manner of a simple beam.
