摘要： PURPOSE:To increase the rate of heat exchange between gas before suction and gas after discharge compared with a case where an exhaust port is installed to the side of a cylinder by insulating both suction gas and exhaust gas in an adiabatic expansion engine provided with an exhaust port installed in a motion direction of a piston in structure. CONSTITUTION:A sleeve 2 is installed to the outer periphery of a cylinder 1, all of which are housed in a vacuum vessel, thereby insulating their interface with the outside. A head wall 5 is provided with an exhaust port 17 whose diameter is smaller than a pad 15 of an exhaust valve 112, thereby forming a series of exhaust passage which leads to an outside piping 20 by way of an insulation passage 18 and an exhaust passage 19. The insulation passage 18 is a part of an insulation member 21 which is connected with a cylinder core 22 mounted to the head wall 5, and a suction valve chamber 9. A connection section 23, which covers a suction port 6, has a thin wall and is long and narrow, and forms the insulation member 21 and a space 24. On the other hand, a space 25 formed by the suction valve chamber 9 and the cylinder core 22 is enclosed under vacuum state.

摘要： PURPOSE:To improve the bonding strength of fluorine plastic remarkably by a method wherein groove-like steps are provided between the fluorine plastic and a matter to be bonded to the plastic, while adhesive agent is interposed between them. CONSTITUTION:Grooves 4 are provided on the peripheral direction of the side surface of fluorine plastic 1. The groove 4 is provided on the surface receiving a shear force with respect to a force applied to the fluorine plastic from an arrow sign direction in the diagram. Therefore, the side surface of the fluorine plastic 1 comes in a configuration having steps with respect to the direction of the shear force. The fluorine plastic 1 and a metallic material 2 are bonded by filling an adhesive agent 5 between them and curing it. The cured adhesive agent 5 enters into the groove 4 of the fluorine plastic and serves as keys, whereby it becomes very hard to separate the fluorine plastic 1 from the metallic material 2.

摘要： PURPOSE: To keep a distance between an acting point of compressed gas and an input shaft axis of a joint constant as well as prevent a torque variation from occurring, by letting the input shaft axis of a crank joint accord with a base circle center of an involute-form fixed scroll blade.
CONSTITUTION: An axis T
1 of a rotary shaft 70 of a crankshaft 72 in this scroll compressor is made to accord with a base circle center of an involute of a fixed scroll blade 25. Therefore, a distance between an acting point of compressed gas force acting on a scroll blade 34 and the rotary shaft axis T
1 is kept constant in consequence, leading to a drop in torque variations so that noise and vibration are prevented from occurring. When the scroll blade is formed by semicircular connection, it will do that an intermediate point between the semicircular center most approximate to the center of the fixed scroll blade and the semicircular center secondly approximate to the center is merely made to accord with the rotary shaft axis T
1 .

摘要： PURPOSE:To improve the workability, productionability and the abrasion resistance at the sliding section by forming fixed scroll and swivel scroll with such material as mainly composed of synthetic resin while integrally providing abrasion-resistant material at the sliding section of both scrolls. CONSTITUTION:Since the fixed scroll 5 and the swivel scroll 11 in scroll compressor are formed with proper synthetic resin such as plastic, they are light and have excellent workability and machining after molding may be performed as required in short time. While since abrasion-resistant members 23, 25 are provided integrally at the sliding section of said scrolls 5, 11, the abrasion-resistance is improved to lengthen service life. Consequently, highly accurate fixed and swivel scrolls 5, 11 can be mass produced resulting in mass production of scroll compressors with low cost.
