Title
(EN) A WEIGHING VALVE DEVICE
(FR) DISPOSITIF A SOUPAPE DE PESEE
Abstract
(EN)
A weighing valve device comprises a housing (101) with a cover (104) , an axially movable piston (102) in a bore in the housing (101) and an enclosed body (103) of plastically deformable material in the piston (102). A differential piston (105-107) with a smaller diameter piston part (106) is in contact with the body (103) and with a larger diameter piston part in the form of a diaphragm (105) clamped between the housing (101) and the cover (104) and backed by a disc (107). A valve with an axially movable, spring-biassed valve member (110) is in contact with the diaphragm. A compressed air pressure acting on the diaphragm (105) and governed by the valve is adapted to counteract a mechanical force on the piston (102). The smaller diameter part (106) of the differential piston (105-107) rests against the disc (107) at its center. The diaphragm (105) and the disc (107) are provided at their centres with a through passage (111) for venting of compressed-air. The valve member (110) is arranged over the through passage (111). The smaller diameter piston part (106) is guided by a guide sleeve (108') in a guide block (108) above the enclosed body (103).

Dispositif à soupape de pesée comportant un boîtier (101) muni d'un couvercle (104), un piston (102) mobile axialement dans un alésage du boîtier (101) et un corps (103) enfermé en matériau déformable plastiquement dans le piston (102). Un piston différentiel (105-107) comportant une partie (106) de piston de plus petit diamètre est en contact avec le corps (103) et avec une partie de piston de plus grand diamètre sous la forme d'un diaphragme (105) serré entre le boîtier (101) et le couvercle (104) et soutenu par un disque (107). Une soupape comportant un élément (110) de soupape mobile axialement sollicité par ressort est en contact avec le diaphragme. Une pression d'air comprimé agissant sur le diaphragme (105) et régulée par la soupape est adaptée de façon à contrebalancer un effort mécanique sur le piston (102). La partie (106) de plus petit diamètre du piston différentiel (105-107) s'appuie contre le disque (107) en son centre. Le diaphragme (105) et le disque (107) sont pourvus au niveau de leurs centres d'un passage (111) débouchant destiné à l'évacuation de l'air comprimé. L'élément (110) de soupape est agencé par-dessus le passage (111) débouchant. La partie (106) de piston de plus petit diamètre est guidée par un manchon (108') de guidage dans un bloc (108) de guidage au-dessus du corps (103) enfermé.
