摘要： PURPOSE:To promote the proper retention of thrust force received by a turning scroll in its operation by installing a recess, where gas in a compression space is guided, on the back of an end plate of this turning scroll, and hermetically sealing this recess with a sliding-contact member. CONSTITUTION:Turning power out of a balancer shank 21 of a main shaft 11 imparts a turning motion with no rotation to a turning scroll 25 via an Oldham's mechanism 39 and thereby gas inhaled from a suction port is compressed in proportion as capacity in compression space 37 lessening toward the center in corresponding to the turning motion, and then this compressed ags is discharged out of a discharge port 43 installed in a fixed scroll 23. In this case, a recess 45 is installed in a backside 33a of an end plate 33 of the turning scroll 25. This recess 45 is hermetically sealed with a ring-form sliding- contact member 47, and interconnected to the compression space 37 via a gas passage 49 piercing through the end plate 33. With this constitution, the gas in the midway of compression is guided into the recess 45 and the compression space 37, whereby the balance of a resultant between the compression space side and the backside of the turning scroll is made so as to be optimally secured.

摘要： PURPOSE:To provide possibility of high efficiency operation over a wide range by furnishing the discharge port with a discharge valve which is opened at a specified discharge pressure. CONSTITUTION:A discharge port 39 is in communication with a discharge pipe 5 via a discharge muffler 41 and discharge passage 43 and is fitted with a discharge valve 45 which is opened at a specified discharge pressure. A compression chamber 33 is formed involving a capacity decrement gradually toward the center in the cyclic motion attaining the discharge pressure from the suction pressure with revolution of scrol 21 during operation at the min. compression ratio, and when the refrigerant is compressed to attain the specified pressure, a discharge valve 45 is opened, so that there is no risk of shortage in compression to ensure that operation takes place with good efficiency. During operation from the min. compression ratio to the max., a compression chamber 33 is formed involving a decrement of the capacity gradually toward the center, and when the refrigerant is compressed to cause attainment of the specified pressure, the discharge valve 45 is opened. This eliminates rapid over- compressing to allow avoiding a pressure loss, and operation with good efficiency can be made over a wide scope.

摘要： PURPOSE:To prevent application of an excessive load on each spiral blade in a fluid compressor embodied in the spiral blade system by furnishing an opening/closing valve which is facing a plurality of working chambers partitioned by the blades and releases the pressure from a working chamber on the high pressure side toward a working chamber on the low pressure side. CONSTITUTION:When current is fed to a motor-driven element 9 for rotating a cylinder 17 constructed in a single piece with a rotor 15, a rotary body 21 is turned through an Oldham ring 23. Because this rotary body 21 makes eccentric rotation, a relative velocity is generated between its peripheral surface and the bore of the cylinder 17 facing the same 21 to cause its revolving relative to the cylinder 17. As a result, the fluid sent into the working chamber 35 on the suction side is compressed while fed one bit by bit to the working chamber 35 on the discharge end side. In this type of compressor, an opening/closing valve 43 is formed at the cylinder 17 in such a way as facing the working chamber 35 on the high pressure side and is operated so that it opens, when a large amount of fluid is confined in the working chamber 35 to put the inside thereof in the overcompressed state, and closes when this overcompressed state goes out.

摘要： PURPOSE:To improve compression efficiency and ensure a low noise by causing the retreat of one of stepped sections formed in the scroll body and groove of a revolving or stationary scroll toward a peripheral direction, and causing the advance of a stepped section in the stationary scroll toward a spiral center direction. CONSTITUTION:A stationary scroll 19 and a revolving scroll 21 constituting a compressor section 9 are respectively so formed as to have scroll bodies 27 and 37 spirally rising from the outer sides of bases 25 and 35 toward the centers thereof. The scroll bodies 27 and 37, and peripheral grooves 29 and 39 between the bodies 27 and 37 are so formed as to have two steps, increasing in height from outer peripheral groove end toward a center in steps, via each of stepped sections 31 and 33, and 41 and 43. In this case, for a design point (a) where an Oldham's mechanism itself is assumed to have no play, the stepped sections 41 and 43 of the revolving scroll 21 are caused to retreat by the predetermined amount relative to the center thereof, while the stepped sections 31 and 33 of the stationary scroll 19 are so formed as to advance toward a scroll center. According to this construction, efficient compression can be obtained, and a noise can be reduced.

摘要： PURPOSE:To enable capacity control without using an inverter in a fluid compressor of spiral blade system by separating refrigerant into gas refrigerant and liquid refrigerant by a gas-liquid separator, and leading the separated gas refrigerant into an operating chamber in the compression process. CONSTITUTION:Refrigerant compressed by a fluid compressor 3 so as to have high temperature and high pressure passes a condenser 11, a first capillary tube 49, a gas-liquid separator 51, a second capillary tube 53 and an evaporator 9, and is returned to the suction pipe of a fluid compressor 3 after completing work. This cycle is repeated. In the case of attaining capacity-up at this action time, a control part 55 is opened to feed the upper layer part gas refrigerant G1, separated at the gas-liquid separator 51, into an operating chamber. In this case, a pressure-enthalpy diagram cycle is to pass d, e, f from a, b, c. Cooling capacity, for instance, is to become G(hf-he), where refrigerant quantity flowing into the operating chamber is Gkg/h and led-in gas refrigerant quantity is gkg/h, so that the cooling capacity is raised by the G(hb-he) part compared to the cooling capacity G(hf-hb) of the standard refrigerating cycle.

摘要： PURPOSE:To suppress loss of motive power in various driving conditions, so as to improve driving efficiency by providing a restrictor on a suction tube of a closed case in which a scroll compressor is housed, and whereby controlling the opening of the restrictor based on various driving conditions. CONSTITUTION:A coolant absorbed from a suction tube 3 into a closed case 1 is compressed by a compressor chamber formed out of a fixed scroll and a turning scroll, and the coolant is discharged from a discharging tube 5, in a scroll compressor. In this structure, a restrictor 7 is arranged on the suction tube 3. The switching of the restrictor 7 is controlled by a control part 9, and the flow of the coolant sucked into the closed case 1 is adjusted thereby. Information of pressure difference between the suction tube 3 and the discharging tube 5, temperature difference between outside temperature and a set temperature, or of pressure difference between a designed compression ratio and an actual compression ratio, changed according to various driving conditions, is input into the control part 9 from each sensor. When the pressure difference is small, for example, opening of the restrictor 7 is reduced.
