Abstract

L'invention concerne un piston (3) pour turbomachine, un carter (2) et une vanne de commande (6) configurée pour commander le déplacement du piston (3). L'intérieur du carter (2) comprend une première chambre (23) et une deuxième chambre (25) séparée de la première chambre (23) par le piston (3). La vanne (6) comprend un premier orifice (C), et un deuxième orifice (D) relié fluidiquement à la première chambre (23). Selon l'invention, une première branche de dérivation (84) est située en dérivation du premier orifice (C) et du deuxième orifice (D), la première branche de dérivation (84) étant reliée fluidiquement au conduit de refroidissement (50).The invention relates to a piston (3) for a turbomachine, a housing (2) and a control valve (6) configured to control the movement of the piston (3). The interior of the housing (2) comprises a first chamber (23) and a second chamber (25) separated from the first chamber (23) by the piston (3). The valve (6) comprises a first orifice (C), and a second orifice (D) fluidly connected to the first chamber (23). According to the invention, a first bypass branch (84) is located bypassing the first orifice (C) and the second orifice (D), the first bypass branch (84) being fluidly connected to the cooling duct (50).
