Title (EN) PRESSURE BOOSTER
(FR) MULTIPLICATEUR DE PRESSION
(JA) 増圧装置
Abstract:
(EN) This pressure booster (10) having arranged therein drive cylinders (14, 16) on both sides of a boosting cylinder (12) is provided with: a pair of pilot valves (72, 74) that are actuated when pistons (36, 38) of the drive cylinders abut against the moving ends thereof; and a pair of actuation valves (48, 52) that switch the supply state of a pressure fluid to pressure chambers (24a, 26a) of the drive cylinders. When the pilot valves are actuated, the pressure fluid passes through the pilot valves and is supplied to the pair of actuation valves, and the supply state of the pressure fluid is switched.
(FR) L'invention concerne un multiplicateur de pression (10) dans lequel sont agencés des vérins d'entraînement (14, 16) de part et d'autre d'un vérin d'amplification (12), qui est pourvu : d'une paire de soupapes pilotes (72, 74) qui sont actionnées lorsque des pistons (36, 38) des vérins d'entraînement viennent en butée contre les extrémités mobiles de ces dernières ; et une paire de soupapes d'actionnement (48, 52) qui commutent l'état d'alimentation d'un fluide sous pression vers des chambres de pression (24a, 26a) des vérins d'entraînement. Lorsque les soupapes pilotes sont actionnées, le fluide sous pression passe à travers les soupapes pilotes et est fourni à la paire de soupapes d'actionnement, et l'état d'alimentation du fluide sous pression est commuté.
(JA) 増圧装置(10)は、増圧用シリンダ(12)の両側に駆動用シリンダ(14、16)を配設したものであって、駆動用シリンダのピストン(36、38)がその移動端で当接しているときに作動する一対のパイロット弁(72、74)と、駆動用シリンダの加圧室(24a、26a)に対する圧力流体の供給状態を切り換える一対の作動弁(48、52)とを備え、パイロット弁が作動すると、圧力流体がパイロット弁を通じて一対の作動弁に供給され、圧力流体の供給状態が切り換わる。
