Title
(EN) HYDRAULIC CONTROL VALVE AND HYDRAULIC CONTROL DEVICE
(FR) VALVE À COMMANDE HYDRAULIQUE ET DISPOSITIF À COMMANDE HYDRAULIQUE
(JA) 油圧制御バルブおよび油圧制御装置
Abstract
(EN)
A hydraulic control valve (1) is configured in such a manner that: a positive-pressure chamber (7) to which an inlet port (11) and an outlet port (12) are open is formed on one side of a piston (5) which moves back and forth in the axial direction within a cylinder section (4); a back-pressure chamber (8) is formed on the other side of the piston (5); a valve body (6) which opens and closes the outlet port (12) is provided connected to the piston (5); the positive-pressure chamber (7) and the back-pressure chamber (8) are connected to each other through an orifice (20); a pilot valve (3) which selectively connects the back-pressure chamber (8) to a portion (13) having a lower pressure than the back-pressure chamber (8) is provided in the hydraulic control valve (1); the inlet port (11) is connected to a high-pressure section (10); and the outlet port (12) is connected to the low-pressure section (13) having a lower pressure than the high-pressure section (10). The hydraulic control valve (1) is provided with an orifice adjustment mechanism which adjusts the degree of opening of the orifice (20) on the basis of the state of reduction in hydraulic pressure in the back-pressure chamber.

L'invention concerne une valve à commande hydraulique (1) configurée d'une telle manière que : une chambre à pression positive (7) sur laquelle donnent un orifice d'admission (11) et un orifice de sortie (12) est formée d'un côté d'un piston (5) qui se déplace en un mouvement de va-et-vient dans le sens axial à l'intérieur d'une section de cylindre (4) ; une chambre de contre-pression (8) est formée de l'autre côté du piston (5) ; un corps de valve (6) qui ouvre et ferme l'orifice de sortie (12) est connecté sur le piston (5) ; la chambre à pression positive (7) et la chambre de contre-pression (8) sont connectées l'une à l'autre par le biais d'un orifice (20) ; une valve pilote (3) qui connecte sélectivement la chambre de contre-pression (8) sur une partie (13) ayant une pression inférieure par rapport à la chambre de contre-pression (8) est disposée dans la valve à commande hydraulique (1) ; l'orifice d'admission (11) est connecté à une section haute pression (10) ; et l'orifice de sortie (12) est connecté à la section basse pression (13) ayant une pression inférieure par rapport à la section haute pression (10). La valve à commande hydraulique (1) comporte un mécanisme d'ajustement d'orifice qui ajuste le degré d'ouverture de l'orifice (20) en fonction de l'état de réduction de la pression hydraulique dans la chambre de contre-pression.
