Twin-action valve for controlling liquid flow between chambers with different pressures comprises a valve chamber with two interconnected cylindrical sealing bodies of different diameters

摘要

Twin-action valve (1) comprises a valve chamber (3) containing molded parts as sealing bodies (8) arranged diametrically to the inner openings of two channels (4, 5). The sealing bodies are two interconnected cylindrical bodies (9, 10) with different diameters. Preferred Features: A first cylindrical body (9) has a diameter similar to the internal diameter of the valve chamber. The diameter of a second cylindrical body (10) corresponds to the internal diameter of a pressure spring (11) with which the sealing bodies lie under tension on the inner ends (7) of the valve chamber.
