Title (EN) FLUID CIRCUIT FOR AIR CYLINDERS
(FR) CIRCUIT HYDRAULIQUE POUR VÉRINS PNEUMATIQUES
(JA) エアシリンダ用流体回路
Abstract:
(EN) A fluid circuit (10) for air cylinders is provided with a switching valve (14), an air supply source (16), an exhaust port (18), and a check valve (20). When the switching valve is in a first position, one cylinder chamber (32) is connected with the air supply source, and the other cylinder chamber (34) is connected with the exhaust port. When the switching valve is in a second position, the one cylinder chamber is connected with the other cylinder chamber via the check valve, and the one cylinder chamber is connected with the exhaust port. The acoustic velocity conductance of a pipe (40) connecting the switching valve and a cylinder port part (36) of the one cylinder chamber is lower than the acoustic velocity conductance of the switching valve and the cylinder port part of the one cylinder chamber.
(FR) L'invention concerne un circuit hydraulique (10) pour vérins pneumatiques. Le circuit hydraulique est pourvu d'une soupape de commutation (14), d'une source d'alimentation en air (16), d'un orifice d'échappement (18) et d'un clapet anti-retour (20). Lorsque la soupape de commutation est dans une première position, une chambre de vérin (32) est reliée à la source d'alimentation en air et l'autre chambre de vérin (34) est reliée à l'orifice d'échappement. Lorsque la soupape de commutation est dans une seconde position, la chambre de vérin est reliée à l'autre chambre de vérin par l'intermédiaire du clapet anti-retour, et la chambre de vérin est reliée à l'orifice d'échappement. La conductance de la vitesse acoustique d'un tuyau (40) reliant la soupape de commutation et une partie orifice de vérin (36) de la chambre de vérin est inférieure à la conductance de la vitesse acoustique de la soupape de commutation et de la partie orifice de vérin de la chambre de vérin.
(JA) エアシリンダ用流体回路(10)は、切換弁(14)、エア供給源(16)、排気口(18)およびチェック弁(20)を備え、切換弁の第1位置において、一方のシリンダ室(32)がエア供給源に連通するとともに他方のシリンダ室(34)が排気口に連通し、切換弁の第2位置において、一方のシリンダ室がチェック弁を介して他方のシリンダ室に連通するとともに一方のシリンダ室が排気口に連通し、一方のシリンダ室のシリンダポート部(36)と切換弁との間を接続する配管(40)の音速コンダクタンスが一方のシリンダ室のシリンダポート部および切換弁の音速コンダクタンスより小さい。
