摘要： PURPOSE:To prevent the generation of thermal deformation of a case during welding as well as a leakage of refrigerant without fail by welding a guide pipe to a connecting pipe insertion hole of a case in advance. CONSTITUTION:A guide pipe 13 is brazed to a case 1 with silver solder 14 for example before compression elements such as a cylinder housing 2 are built in the case 1. A connecting pipe 15 is inserted into a refrigerant suction hole 6 of the cylinder housing 2 through the guide pipe 13. A ring-shaped bank 16 is formed near the end projecting outside of the case 1 of the connecting pipe 15. As the guide pipe 13 is soldered to the case 1 to allow a communication between the outside and inside of the case 1 before the pressure element such as the cylinder housing 2, etc., are stored and fastened inside the case 1, the generation of thermal deformation of the case 1 can be prevented. At the same time, this construction allows each connecting part- the connection between the case 1 and the guide pipe 13 and the connection between the guide pipe 13 and the connecting pipe 15 and the connecting pipe 15 and the suction pipe 10 to be easily connected with welding and prevents the generation of refrigerant leak without fail.

摘要： PURPOSE: To improve the wear resistance of the bearing of a compressor by using a molding of a sintered material in forming said bearing, embedding a metallic material which melts when calcined and forms a fluid passage in the bearing into said molding and sealing the sintered material with the molten metal.
CONSTITUTION: A main bearing 6 and an auxiliary bearing 7 are formed of a monolithic molding of a sintered material, in a hermetic type compressor provided with an electric motor 2 housed in the upper part in a hermetic casing 1 which can be divided to upper and lower parts and a compressor 5 coupled directly to the motor 2. An annular fluid passage 14 formed in the bearing 7 is formed in the following way: A metallic tubular body or bar-like body 15 formed of a metallic material which melts when calcined is preliminarily embedded into a monolithic molding 7 formed of a sintered material and the body 15 is melted in the stage of calcination to form the passage 14 with the space made after the melting. The sintered material is sealed by the molten metal and at the same time the wear resistance of the bearing 7 is improved by the same. A through- hole for the discharge valve 12 of the bearing 6 is similarly formed of a tubular body 15.

摘要： PURPOSE:To reduce a noise by a method wherein a partition plate is provided with a resonant type sound reducer comprising a tin pipe part opened at a side part of a communication hole and a vacant part forming a resonant chamber communicating with the tin pipe part. CONSTITUTION:A closed container 21 is constructed such that its inner part is partitioned by a partition plate 24 into an upper chamber 21a at a side of an inlet pipe 22 and a lower chamber 21b at a side of an outlet pipe 23, respectively. An upper surface of the partition plate 24 is covered by an upper convex filter 25, for example, and a plurality of communication holes 26 are formed in a direction passing through a plate thickness direction. Each of sound reducing parts 29 has a tin pipe part 29a opened at a side of each of communication holes 26 and a circular cavity 29b having a circular bottom surface. The cavity 29b is formed with a resonant chamber 29c communicating with the tin pipe part 29a within it. Although the gas contains pressure pulsation components in a wide range, when the refrigerant gas passes through each of the communication holes 26..., the gas is separated into gas and liquid, thereby sound of the refrigerant gas is attenuated under a series resonation action of the tin pipe part 29a of each of the sound absorbing portions 29 and a resonant chamber 29c of a cavity 29b and then a sound reducing effect can be attained.

摘要： PURPOSE:To enable a compression mechanism part to be set in a condition that its blade is directed in a direction except the perpendicular, by providing an extending passage which extends a lubricating oil suction port of a blade oil pump mechanism being directed to a side of the internal bottom part of an enclosed case. CONSTITUTION:An extending passage 26, which extends a lubricating oil suction port 19 of a blade oil pump mechanism 14 toward the internal bottom part side of an enclosed case 1, is formed between a swollen part 25 in a portioning plate 22 and a cylinder. In this way, in accordance with the reciprocating action of a blade 11, lubricating oil, accumulating in the internal bottom part of the enclosed case 1, is introduced into a main passage through the extending passage 26 of the blade oil pump mechanism 14, and a compression mechanism part 4 enables the blade 11 to be set in a condition that it is placed being directed almost in the horizontal direction. Accordingly, a compressor enables the dimension of its total height to be low formed while the improvement of durability to be promoted by preventing a peripheral equipment or the like from easily touching a suction pipe 13 further the improvement of reliability to be promoted by containing a proper amount of lubricating oil in the inside of the enclosed case 1.

摘要： PURPOSE:To damp and suppress the high-order vibration mode by means of an elastic plate by installing one edge part of the elastic plate between a valve fixing surface and a reed valve and extending the free edge part of the elastic plate so as to be opposed to the concaved part between the valve fixing surface and a valve seat surface. CONSTITUTION:The secondary vibration is generated in a reed valve 8, in addition to the primary vibration by repeating, in a number of times per unit time, the ON/OFF operation of the reed valve 8. However, an elastic plate 7 damps the secondary vibration of the reed valve 8 and suppressed generation of vibration. Particularly, if the effective length of the elastic plate 7 is set more than the half of the effective length of the reed valve 8, the elastic plate 7 suppresses the peak part of the secondary vibration mode, and the effective damping can be achieved.

摘要： PURPOSE:To secure a discharge valve with normal opening/closing operation for a long period of time by constructing a compressor in such an arrangement that a discharge valve and a valve holder are installed within a recess-shaped valve chamber provided at the bearing outer surface of compressor, forming this valve chamber from a major dia. part and a comparatively narrow groove, and shaping the valve holder in a certain appropriate form. CONSTITUTION:In the compressor part of an enclosed compressor machine the main bearing part 1 is provided with a recess-shaped valve chamber 2 as facing outward, and a discharge hole 3 leading to the compression chamber is formed at the bottom of the valve chamber 2. A discharge valve 4 is arranged in the valve chamber 2 and fixed to a valve seat 6 by screws 7 etc. together with a valve holder 5, which limits the height of the discharge valve at its opened time. The valve chamber 2 is formed from a major dia. part 2a, where the discharge hole 3 is provided, and a groove 2b leading therefrom till the valve seat 6. The valve holder 5 is equipped with bosses 5c in a place of groove 2b near the major dia. part 2a on both sides, wherein the tips of these bosses 5c are apart at a distance (t) near the width T of the groove 2b. Thereby the discharge valve 4 is prevented from dislocation to ensure that the valve make good opening/closing operation for a long period of time.
