Improved valve with elastomer seal
An actuator (4) moves a rod (3) attached to a first part (6) of a piston (1). The second part (5) is the O-ring and the thir part (7) forms the expanded top end of a hollow rod (13). This rod fits into a support at the bottom. The first and third parts of the piston may be screwed together, and may...

| description | An actuator (4) moves a rod (3) attached to a first part (6) of a piston (1). The second part (5) is the O-ring and the thir part (7) forms the expanded top end of a hollow rod (13). This rod fits into a support at the bottom. The first and third parts of the piston may be screwed together, and may have shallow grooves which hold and compress the r while causing it to expand outward to seal against the cylindrical valve seat (2).
La vanne à clapet comporte un clapet (1) en forme de piston mobile dans un siège cylindrique (2). Ce clapet (1) est solidaire d'une tige de commande (3) s'étendant dans l'axe du siège cylindrique (2). Le clapet comprend deux éléments de clapet (6, 7) fixés axialement l'un à l'autre par des moyens de serrage, chacun de ces deux éléments comportant une gorge annulaire de section sensiblement en forme de demi-cercle ouverte vers la gorge portée par l'autre élément, le joint (5) torique en élastomère étant logé entre les deux gorges annulaires et serré entre celles-ci par lesdits moyens de serrage. |
