Title (EN) HYDRAULIC ACTUATOR WITH PRESSURE AMPLIFIER
(FR) ACTIONNEUR HYDRAULIQUE À AMPLIFICATEUR DE PRESSION
Abstract:
(EN) A hydraulic actuator (1) is disclosed comprising a cylinder housing (2), a piston (5) with a piston rod (6) being displaceably arranged inside the cylinder housing (2) and a pressure amplifier (10) comprising an inlet section (18) with a pressure inlet port (20), an active section (19) with a high pressure outlet port (22), a low pressure chamber (32) and a high pressure chamber (38a). It is an objective of the invention to provide a hydraulic actuator (1) with a modular pressure amplifier (10). To this end, the inlet section (18) is arranged inside the piston rod (6), and wherein the low pressure chamber (32) is stationarily arranged relative to the inlet section (18).
(FR) Actionneur hydraulique (1) comprenant un carter de cylindre (2), un piston (5) pourvu d'une tige (6) de piston agencé de manière déplaçable à l'intérieur du carter de cylindre (2) et un amplificateur de pression (10) comprenant une section d'entrée (18) dotée d'un orifice d'entrée de pression (20), une section active (19) dotée d'un orifice de sortie haute-pression (22), une chambre basse-pression (32) et une chambre haute-pression (38a). Un objectif de l'invention est de fournir un actionneur hydraulique (1) doté d'un amplificateur de pression modulaire (10). À cet effet, la section d'entrée (18) est disposée à l'intérieur de la tige (6) de piston, et la chambre basse-pression (32) est agencée de manière fixe par rapport à la section d'entrée (18).
