Abstract

Compresor de gas que comprende un órgano de movimiento alternativo (2) que constituye una pared móvil de una cámara de compresión para aumentar y reducir cíclicamente su volumen al objeto de inducir y alimentar gas comprimido a una boca de alimentación (10); una válvula de descarga que forma parte íntegra de la culata del compresor y que incluye un elemento de válvula obligado (15) que actúa en un sentido para cerrar un conducto de ventilación (17) en comunicación con la referida camára, funcionando la válvula de descarga por una señal de fluido a presión que actúa sobre un área sensible a lapresión (24) de la misma en un sentido para contrarrestar el empuje y ventilar por lo tanto la cámara de compresión durante las carreras de compresión del referido elemento, caracterizado porque la válvula tiene otro área (20) sujeta a la presión existente en la cámara de compresión, por lo que la referida presión actúa sobre la misma en un sentido para ayudar al empuje del muelle.Gas compressor comprising an alternative movement member (2) that constitutes a mobile wall of a compression chamber to cyclically increase and decrease its volume in order to induce and supply compressed gas to a supply mouth (10); a discharge valve that is an integral part of the compressor cylinder head and that includes a forced valve element (15) that acts in one direction to close a ventilation duct (17) in communication with said chamber, the discharge valve operating by a signal of fluid under pressure that acts on an area sensitive to pressure (24) thereof in one direction to counteract the thrust and therefore ventilate the compression chamber during the compression strokes of said element, characterized in that the valve it has another area (20) subject to the pressure existing in the compression chamber, so that said pressure acts on it in one direction to help push the spring.
