Abstract

TAMPA DE DISTRIBUIÇÃO PARA MEDIDOR DE GÁS COM MEMBRANAS DE ACIONAMENTO DE DISTRIBUIÇÃO ROTATIVA. A presente invenção refere-se a um medidor de gás, compreendendo várias câmaras de medida e uma gaveta (2) de distribuição rotativa em torno de um eixo de rotação sobre a superfície superior de uma tampa (1) de distribuição que apresenta várias aberturas (10-12) ligadas, cada uma a uma câmara de medida, a gaveta (2) permitindo ao gás entrar e sair alternadamente das câmaras de medida no decorrer de sua rotação em torno do eixo de rotação, e a tampa (1) comportando pelo menos duas coroas de estanqueidade (15a, 15b) concêntricas em relação ao eixo fixo, sobre a borda superior plana das quais deslizam superfícies de contato (25, 26) da gaveta. De acordo com a invenção, a borda superior plana (15d) de pelo menos uma das coroas de estanqueidade apresenta uma forma não-circular definida, de maneira que qualquer ponto da superfície de contato, que fica em frente essa borda superior plana (15d) de forma não-circular, se encontre, pelo menos uma vez sobre uma rotação, sem contato com essa borda. A vantagem da invenção é que a favorece a mesma evacuação de agentes contaminadores.DISTRIBUTION COVER FOR GAS METER WITH ROTATING DISTRIBUTION DRIVE MEMBRANES. The present invention relates to a gas meter, comprising several measurement chambers and a distribution drawer (2) rotating around an axis of rotation on the upper surface of a distribution cover (1) which has several openings ( 10-12) each connected to a measuring chamber, the drawer (2) allowing the gas to alternately enter and exit the measuring chambers in the course of its rotation around the axis of rotation, and the lid (1) comprising at least at least two sealing rings (15a, 15b) concentric with respect to the fixed axis, on the flat upper edge of which the contact surfaces (25, 26) of the drawer slide. According to the invention, the flat upper edge (15d) of at least one of the sealing crowns has a defined non-circular shape, so that any point on the contact surface facing this flat upper edge (15d) in a non-circular fashion, meets, at least once on a rotation, without contact with that edge. The advantage of the invention is that it favors the same evacuation of contaminating agents.
