摘要： PURPOSE:To operate a selector valve with a minor force by allowing the driving force applied to one of the two-way selector valve to work also as driving the other two-way selector valve. CONSTITUTION:A No.1 two-way selector valve 10 is furnished, which puts one of the alternative ports 16 in communication with a support port 15 at normal time and puts the port 16 in communication with No.1 exhaust port 18, while a No.2 two-way selector valve 40 is installed which puts the other port 17 in communication with No.2 exhaust port 19 at normal time and puts the port 17 in communication with the supply port 15 when drive force is applied. When this No.2 two-way selector valve 40 puts the other port 17 in communication with the supply port 15, its pressure is utilized as drive force for No.1 two-way selector valve 10.

摘要： PURPOSE:To remove a slidable part and permit the captioned valve to be operated by a small switching operation force by installing a valve body onto the front and back surfaces of the both top edge parts of a valve arm which can shift, elevate and lower. CONSTITUTION:In the nonconduction state of a solenoid 14 to a coil 16, a valve arm 12 is lowered by the force of a compression spring 17. In this state, the pressure fluid supplied from a compressed air source P is introduced into a diaphragm chamber 23r from an inport 23, and sent into a pressure chamber 32 from a feeding port 27. A pressure chamber 31 communicates to a discharge port 24 through a feeding port 26 and the diaphragm chamber 24r. Therefore, the valve arm 12 is applied with a turning moment in the clockwise direction, and can surely close a discharge port 25 onto which the fluid pressure supplied from the compressed air source is applied.

摘要： PROBLEM TO BE SOLVED: To provide a damping material which can be manufactured using a comparatively simpler mold and at a low price. SOLUTION: A clamping material body 1 is manufactured of at least one kind of rubber selected from among a styrene-butadiene rubber, an ethylene- propylene-diene three-dimensional polymer, an ethylene-propylene copolymer obtained by copolymerizing an acid component, a nitrile rubber, a hydrotreated nitrile rubber, a nitrile rubber obtained by copolymerizing an acid component, an ACM rubber, a fluororubber and a silicone rubber. In addition, a thermoplastic resin film 4 selected between a polyphenylene ether and a polyamide with an amino group at the terminal is bonded to the compression face 11 of the damping body 1 during vulcanizing the described rubber. Consequently, it is possible to effectively prevent the compression end face from being deviated when a load is applied to the damping body 11. Further, the damping body 11 can be easily and cheaply manufactured by means of a mold which can be split into two halves. COPYRIGHT: (C)2003,JPO

摘要： PURPOSE:To open and close a high pressure valve while using small pilot pressure by converting the linear motion of a piston moved by air pilot pressure into the swing motion of a power lever so that the motion of the piston may be transferred to a slider after boosted. CONSTITUTION:When air pilot pressure P is applied from an inlet hole 28 to a chamber 27, a piston 23 moves down. A power lever 33 is pushed by this moving down and swing around a fixed shaft 34, and the cam face of the fixed shaft 34 moves up a follower, that is, slider 24. This moving up power is boosted depending upon the lever ratio of the power lever 33 determined by the distance between the shaft 34 and a roller 35 and the distance (s) between the cam face 36 and the shaft 34. Therefore, such big power as being capable of opposing to a stacked coned disc spring 32 can be generated by small power only making the piston 23 move down resulting in the rise of a slider 24.

摘要： PURPOSE:To simultaneously control a plural number of passages by arranging a plural number of valve bodies concentrically, supporting them with a diaphragm in the floating state and attracting this plural number of the valve bodies simultaneously with a solenoid. CONSTITUTION:A disc type valve body 16 is positioned in a conversion chamber 14 and a circular type valve body 17 concentric with the valve body 16 in a conversion chamber 15 respectively, and each of the valve bodies 16 and 17 has perforated diaphragms 18 and 19 in one body on its respective peripheral part, and their peripheral beat parts 18a and 19a are sandwiched between split housings 11 and 12, and consequently, the valve bodies 16 and 17 are respectively supported in the floating state in the conversion chambers 14 and 15. Then, when a solenoid valve is electrified, the valve bodies 16, 17 are attracted, and the valve body 16 closes an exhaust port E2 and opens a pressure introduction port 20, and the valve body 17 closes a pressure introduction port 21 and opens an exhaust port E1.. Accordingly, the conversion chamber 14 turns to the high pressure side and the conversion chamber 15 turns to the low pressure side and the passages are reversed, pressure fluid is introduced to a pressure chamber C2, a pressure chamber C1 turns to release air and a piston P lowers.
