The invention relates to a point machine for movable frogs (1) comprising at least one cylinder-piston unit (5) having a defined, pre-set piston stroke. Said cylinder-piston unit (5) is connected to bearings (6), which can be displaced in the axial direction of the piston stroke, and is connected to a fixed substructure for setting a defined central position of the piston stroke and of the driver for the moveable frog (1). The driver for the moveable frog (1) is coupled to the cylinder-piston unit (5) while interconnecting stops (9) that can be displaced in an axial direction.

L'invention concerne un appareil de manoeuvre d'aiguille pour coeurs mobiles de croisement (1), comportant au moins une unité cylindre-piston (5) à course de piston préréglée définie. Ladite unité cylindre-piston (5) est reliée à des paliers (6) déplaçables dans le sens axial de la course du piston, lesdits paliers étant reliés à une infrastructure fixe afin d'ajuster une position médiane définie de la course du piston et de l'entraîneur prévu pour le coeur mobile de croisement (1). L'entraîneur prévu pour le coeur mobile de croisement (1) est accouplé à l'unité cylindre-piston (5), avec intercalage de butées (9) déplaçables dans le sens axial.
