Abstract

GAVETA DE DISTRIBUIÇÃO PARA MEDIDOR DE GÁS COM MEMBRANAS DE ACIONAMENTO DE DISTRIBUIÇÃO ROTATIVA. A presente invenção refere-se a um medidor de gás com membranas de acionamento de distribuição rotativo, compreendendo várias câmaras de medida, e uma gaveta (2) de distribuição montada rotativa em torno de um eixo de rotação sobre a superfície superior de uma tampa (1) de distribuição, na qual são feitas várias aberturas que são ligadas, cada uma, a uma câmara de medida, a gaveta (2) de distribuição permitindo ao gás entrar e sair alternadamente das câmaras de medida no decorrer de seu movimento de rotação em torno do eixo de rotação, e a tampa (1) de distribuição comportando uma coroa de estanqueidade externa (15a), sensivelmente concêntrica em relação ao eixo de rotação, sobre a borda superior plana da qual desliza a superfície de contato externo (25) da gaveta de distribuição, formando uma interface (28) de deslizamento entre a coroa de estanqueidade externa (15a) e a superfície de contato externo (25), caracterizado pelo fato de que o medidor de gás comporta, além disso, uma aba de proteção (30) que envolve, de maneira estanque, todo o contorno da superfície de contato externo (25) e apresenta uma parede periférica que se estende em direção a tampa (1), de maneira a recobrir essa interface (28) de deslizamento.DISTRIBUTION DRAWER FOR GAS METER WITH ROTATING DISTRIBUTION DRIVE MEMBRANES. The present invention relates to a gas meter with rotary dispensing drive membranes, comprising several measuring chambers, and a dispensing drawer (2) mounted rotatably about an axis of rotation on the upper surface of a lid ( 1) distribution, in which several openings are made that are each connected to a metering chamber, the distribution drawer (2) allowing the gas to alternately enter and exit the metering chambers in the course of its rotational movement in around the axis of rotation, and the distribution cover (1) comprising an external sealing ring (15a), substantially concentric with respect to the axis of rotation, on the flat upper edge from which the external contact surface (25) of the distribution drawer, forming a sliding interface (28) between the external sealing ring (15a) and the external contact surface (25), characterized in that the gas meter also comprises a and protection (30) that tightly surrounds the entire contour of the external contact surface (25) and has a peripheral wall that extends towards the cover (1), in order to cover this sliding interface (28). .
