摘要： PROBLEM TO BE SOLVED: To prevent the damage of a scroll compressor by providing the end plate of a fixed scroll with a hole to make a high and a low pressure side communicate mutually and moreover a high pressure relief valve in the above hole. SOLUTION: A high pressure relief valve 60 is composed of a ball 62 to abut on a seating face 61 formed in a hole 66, a spring 63 to press energize the ball 62 toward the seating face 61 under fixed setting force, and a spring support 64 to support the one end of the spring 63. During the operation of a scroll compressor, a difference between pressure on a high pressure side 46 and that on a low pressure side 47 attains a fixed value, the ball 62 of the high pressure relief valve 60 separates from the seating face 61 against the bursting force of the spring 63, and the gas on the high pressure side 46 passes through the hole 66 and the high pressure relief valve 60 and flows to the low pressure side 47. The pressure on the high pressure side does not therefore rise above a prescribed pressure for preventing the damage of a scroll compressor.

摘要： PURPOSE:To make an output voltage value of a rotation signal sufficiently large, and improve detecting accuracy of the rotation speed by forming an Oldham's link to check rotation of a turning scroll of a magnetic raw material, and arranged an electromagnetic induction system rotation signal detecting means opposite to this. CONSTITUTION:When a rotary shaft 7 is rotated, a turning scroll 14 is driven in turning through turning driving mechanisms 20, 21 and 25, and revolves while rotation is being checked by an Oldham's link 26. As a result, gas flowed in a compression chamber 19 from a suction chamber 28 moves to a central chamber 22 while being compressed, and push-opens a delivery valve 30 of a delivery port 29, and flows outside of a sealed housing 1 after flowing in a delivery cavity 31. In this way, the Oldham's link 26 is formed of a magnetic raw material. An electromagnetic induction type rotation signal detecting means 50 is arranged opposite to the Oldham's link 26. Thereby, and output voltage value generated in the rotation signal detecting means 50 according to reciprocating motion of the Oldham's link 26 can be made sufficiently large.

摘要： PROBLEM TO BE SOLVED: To lubricate a subbearing by a mist of lubricating oil by providing a gas suction port into a housing in its one end surface and in a position opposed to an internal circumferential side space of a stator coil in an electric motor. SOLUTION: An internal circumferential side space 60, surrounded by a coil Mb1 of a stator Mb in an electric motor M, is formed, and a gas suction part 61 is provided so as to be opposed to the internal circumferential side space 60 in a right end face of a housing 4. When a motor-driven compressor is operated, gas flows in the internal circumferential side space 60 from the gas suction port 61 inverted here, a mist of lubricating oil contained in this gas is separated to lubricate a subbearing 51. A suction fitting block is tightened here by a bolt 65 to the right end face of the housing 4. This lubricating oil, according to rotating a rotary shear, is sucked to a supply oil hole from its one end opening, and the oil, after energized in a process passing in the supply oil hole, is supplied to the subbearing 51 from the other end opening, with the subbearing lubricated.

摘要： PROBLEM TO BE SOLVED: To catch and remove foreign matter contained in intake gas during a process where the intake gas flows through a strainer by installing the strainer in the gas passage of a frame. SOLUTION: During the operation of a scroll type compressor, in a process where intake gas drawn from an intake port into a space 48 on the side of an electric motor M in a housing 4 flows through a strainer 60 installed in a gas passage 54 drilled and provided in a frame 5, the strainer 60 catches and removes foreign matter contained in the intake gas. Thus, since the intake gas having flowed through the strainer 60 is drawn and compressed by the compression chamber 24 of a scroll compressing mechanism C, the foreign matter is not bitten in an engaging face between a fixed scroll 1 and a revolving scroll 2.

摘要： PURPOSE: To eliminate machining and burr removing work for a groove for fixation and thereby reduce the man-hours by inserting a sealed terminal into a mounting hole, and press fitting a bush nut into the mounting hole, wherein the bush nut is inclined a little toward the periphery and has a plurality of pawls whose outside diameter is some greater than the inside diameter of the mounting hole. CONSTITUTION: From the inside opening, a sealed terminal 51 is inserted into a mounting hole 53 penetrating a cover 4, and the front surface is contacted with the shoulder 59 of the mounting hole 53, and then a bush nut 57 is press fitted into the mounting hole 53 and its front surface is put in pressure contact with the rear surface of the terminal 51. The bush nut 57 is provided with a circular hole 57c in the center of the ring-shaped body 57b, and at the periphery of the body 57b, a plurality of pawls 57a inclined backward aslant are formed at a certain spacing in between. The outside diameter D of the pawl 57a is a little greater than the inside diameter (d) of the mounting hole 53. If the terminal 51 is inserted into the mounting hole 53 and the bush nut 57 is press fitted, the pawls 57a bite into the inside surface of the hole 53 to allow the terminal 51 to be secured in the hole 53, which eliminates necessity for use of any groove for fixation.
