Title (EN) VARIABLE STROKE AND CLEARANCE MECHANISM
(FR) MECANISME A COURSE ET ECARTEMENT VARIABLES
Abstract:
(EN) In general, an assembly includes at least one piston housed in a cylinder and a transition arm coupled to the piston. The transition arm is coupled to a member that is housed in a channel defined by a rotating member. Movement of the transition arm adjusts a clearance distance between an end face of the piston and an end wall of the cylinder, and causes the member to slide in the channel such that a stroke of the piston is changed. The member is configured to allow the rotating member to rotate relative to the transition arm and/or configured to allow a change in orientation of the transition arm with respect to the rotating member. In other implementations, the transition arm includes a nose pin and the rotating member is coupled to the nose pin such that axial movement of the transition arm changes an axial position of the piston in the cylinder and causes the nose pin to move relative to the rotating member along an axis other than a central axis of the nose pin.
(FR) L'invention concerne, d'une manière générale, un ensemble comprenant au moins un piston logé dans un cylindre et un bras de transition couplé au piston. Le bras de transition est couplé à un élément lequel est logé dans un canal défini par un élément rotatif. Le mouvement du bras de transition règle la distance d'écartement entre une face terminale du piston et une paroi terminale du cylindre et provoque le coulissement de l'élément dans le canal de telle sorte que la course du piston est changée. L'élément est configuré pour permettre à l'élément rotatif de tourner par rapport au bras de transition et/ou configurer pour permettre un changement d'orientation du bras de transition par rapport à l'élément rotatif. Dans d'autres mises en application, le bras de transition comprend une tige avant et l'élément rotatif est couplé à la tige avant de telle sorte que le mouvement axial du bras de transition change une position axiale du piston dans le cylindre et fait déplacer la tige avant par rapport à l'élément rotatif le long d'un axe autre qu'un axe central de la tige avant.
