Apparatus (10) for use with a valve (11) to perform a grinding operation on the valve. The valve (11) has a valve body (13) defining a valve seat (19) and a valve member (21) moveable into and out of engagement with the valve seat (19). The valve member (21) comprises a valve disc (25) and a valve stem (23). The valve (11) also has a bush (29) through which the valve stem (23) extends in threaded engagement therewith whereby relative rotation between the bush (29) and the valve stem (23) causes axial displacement of the valve stem (23) relative to the bush (29). The apparatus (10) comprises a drive transmission means (55) for providing a driving connection to the bush (29) and the valve stem (23). The drive transmission means (55) has first and second modes of operation, wherein in the first mode of operation the drive transmission means causes the bush (29) to rotate with the valve stem (23) such that the valve stem rotates without undergoing axial movement and wherein in the second mode of operation the drive transmission means (55) causes relative rotation between the bush (29) and the valve stem (23) such that the valve stem undergoes axial movement while rotating. The apparatus (10) has means including hand wheel (245) for selectively causing the drive transmission means (55) to operate in either one of the first and second modes of operation during rotation of the valve stem (23).

La présente invention concerne un dispositif (10) à utiliser avec une soupape (11) pour exécuter une opération de rectification de la soupape. La soupape (11) présente un corps de soupape (13) définissant un siège de soupape (19) et un élément de soupape (21) pouvant s~engager et se désengager du siège de soupape (19). L~élément de soupape (21) comprend une tête de soupape (25) et une tige de soupape (23). La soupape (11) présente également une douille (29) à travers laquelle la tige de soupape (23) s~étend en engagement vissé avec celle-ci, la rotation relative entre la douille (29) et la tige de soupape (23) provoquant ainsi un déplacement axial de la tige de soupape (23) par rapport à la douille (29). Le dispositif (10) comprend un moyen de transmission de l~entraînement (55) permettant un entraînement solidaire de la douille (29) et de la tige de soupape (23). Le moyen de transmission de l~entraînement (55) propose un premier et un second mode de fonctionnement, le moyen de transmission de l~entraînement provoquant, lors du premier mode de fonctionnement, la rotation conjointe de la douille (29) et de la tige de soupape (23) de telle sorte que la tige de soupape tourne sans subir de mouvement axial et le moyen de transmission de l~entraînement (55) provoquant, lors du second mode de fonctionnement, une rotation relative entre la douille (29) et la tige de soupape (23) de telle sorte que la tige de soupape subit un mouvement axial en tournant. Le dispositif (10) présente des moyens incluant un volant de manAEuvre (245) permettant de sélectionner le premier ou le scond mode de fonctionnement du moyen de transmission de l~entraînement (55) durant la rotation de la tige de soupape (23).
