摘要

A double diaphragm pump driven by compressed air, and independent module and retroajustu00e1vel for a double diaphragm pump driven by compressed air. The mechanism of change again for a double diaphragm pump aconada compressed air which comprises a shaft (21) deslizantemente mounted through openings (22) in ainhadas opposite surfaces of double diaphragm chambers (23).In the center of the axis (21) between the two chambers of the diaphragm (23) is provided with an annular groove (24) in which is located an arm (25) extending from a structure in the form of U (26). The structure in the form of U (26) is pivotantemente mounted on a valve plate (27) that includes multiple hole (28).Positioned against a surface of the plate valve (27) is a component of the closure of the valve (29) configured to slide on the surface which selectively the multiple hole (28).The component of closing the valve (29) is held in place by a metallic pins (30) articulately mounted in grooves (31) provided at the extension parallel to the structure in the form of U (26). The linear tensioning springs (32) connect the propellant metal articles (30) with U-shaped structure (26) adjacent to the point of pivotamento.The springs (32) force component of the position of the closing of the valve (29) against the valve plate (27) in a position decentered.
