Abstract: An enclosed compressor which has one or more pores (17) made in the shell of a suction muffler (16) made from a material having a low heat conductivity, such as synthetic resin, and communicating with the inside of an enclosed case (1). The amplification of resonance sounds in the space in the enclosed case (1) is restrained by the pores (17) made at the nodes (18) of the vibration mode of the resonance frequency in the space. The coolant insufficient because of the suction loss consequent on the gas passage resistance of the suction passage for introducing a gas of high suction gas density through a suction pipe (12) into a cylinder (8) by coolant circulation is replenished by sucking the coolant gas in the enclosed case (1) through the pores (17).

Abstract: A hermetic compressor of the present invention is provided with one or more small holes 17 formed in the shell of the suction muffler 16 formed with a low thermal conductivity material such as synthetic resin. The small holes 17 are positioned at nodes 18 in a vibration mode for the resonance frequency of the space formed in the hermetic shell, so that amplification of the resonance sound of the space in the hermetic shell 1 is suppressed. Furthermore, a shortage of the refrigerant is supplemented by the refrigerant gas sucked from the hermetic shell 1 through the small holes 17 when it occurs due to a suction loss caused by the resistance of the flow path for guiding a high density refrigerant gas from the suction tube into the cylinder 8 according to the circulation of the refrigerant.

Abstract: A HERMETIC COMPRESSOR OF THE PRESENT INVENTION IS PROVIDED WITH ONE OR MORE SMALL HOLES 17 FORMED IN THE SHELL OF THE SUCTION MUFFLER 16 FORMED WITH A LOW THERMAL CONDUCTIVITY MATERIAL SUCH AS SYNTHETIC RESIN. THE SMALL HOLES 17 ARE POSITIONED AT NODES 18 IN A VIBRATION MODE FOR THE RESONANCE FREQUENCY OF THE SPACE FORMED IN THE HERMETIC SHELL, SO THAT AMPLIFICATION OF THE RESONANCE SOUND OF THE SPACE IN THE HERMETIC SHELL 1 IS SUPPRESSED. FURTHERMORE, A SHORTAGE OF THE REFRIGERANT IS SUPPLEMENTED BY THE REFRIGERANT GAS SUCKED FROM THE HERMETIC SHELL 1 THROUGH THE SMALL HOLES 17 WHEN IT OCCURS DUE TO A SUCTION LOSS CAUSED BY THE RESISTANCE OF THE FLOW PATH FOR GUIDING A HIGH DENSITY REFRIGERANT GAS FROM THE SUCTION TUBE INTO THE CYLINDER 8 ACCORDING TO THE CIRCULATION OF THE REFRIGERANT.

Abstract: PROBLEM TO BE SOLVED: To save the power consumption and to prevent the breaking and noise and vibration of a discharge pipe by resonance by generating an operation frequency by an inverter device, having a frequency higher than any of the lowest order natural frequencies of a support body and a spring as the lower limit and the lowest order natural frequency of the discharge pipe as the upper limit. SOLUTION: The support body, spring and discharge pipe of an inverter device are resonated at respective operation frequencies C1, C2, C3. Thus, specified frequencies Ca, Cb, Ce (≠ C1, C2, C3) having frequencies higher than C2 causing no resonance in the spring and the discharge pipe as the lower limit and C3 as the upper limit are set. Thus, the discharge pipe is never resonated even if it is operated with the frequency being reduced to the specified frequency Ca in a low load, and the power consumption can be saved. Further, the discharge pipe is never resonated even if it is operated at the specified frequency C3 in a high load, and the capacity can be raised.

Abstract: PROBLEM TO BE SOLVED: To enhance the volumetric efficiency so as to improve the refrigerating capacity by decreasing the loss in suction caused by a flow resistance in a suction passage for leading sucked gas having a high density in a coolant circulating volume from a suction pipe into a cylinder. SOLUTION: In a hermetic compressor, a suction muffler 16 is made of a material such as a synthetic resin having a low thermal conductivity, and in its outer shell more than one of small holes 17 communicated with the inside 1 of a hermetic container 1 are formed. These small holes 17 being located at positions of nodes of a vibration mode at a resonant frequency in the inside space of the hermetic container 1, and accordingly, the amplification of resonating sound in the inside space of the container 1 is restrained while the gas having a high suction density due to the coolant circulating quantity is replenished with coolant gas which is sucked into a space in a cylinder from a suction pipe 12 through the small holes 17, for a deficiency of the coolant caused by a suction loss due to a gas flow resistance in a suction passage through which the gas is led from the suction passage 12 into the cylinder. Thus, the suction loss can be decreased, and accordingly, a hermetic compressor which can decrease its suction loss and can enhance the refrigerating function is provided.

Abstract: PURPOSE:To obtain a closed rotary compressor whose operating noise is less without lowering its efficiency by, in the closed rotary compressor used for refrigerating apparatus for a refrigerating cold storage, utilizing the vertical reciprocatory motion of a vane to open and close a pressure leading-in port communicating with a small volume space, and. opening the above port when the vane is pushed clown during a compression stroke to reduce pressure fluctuation occurring in a cylinder compression chamber. CONSTITUTION:A pressure leading-in port 15 provided in a main bearing end plate 5 communicates with a small volume space 16, and is opened to the inside of a cylinder 6 by utilizing the vertical reciprocatory motion of a vane 9 when the vane 9 is pushed down during a compression stroke.

Abstract: PROBLEM TO BE SOLVED: To provide a closed vessel type compressor which is silent, trouble free and easy to manufacture. SOLUTION: An electric motor element 3, a supporting frame 5 and a compressive element 6 are built-in in a closed vessel 2. The electric motor element 3 is an electric motor composed of a stator 15 and a rotor 16. The stator 15 is employed with a winding of a salient pole concentrated winding type and the winding does not protrude from beneath an annular iron core 70. A lower end of the electric motor element 3 is approximately as high as an upper end of a suspended spring, and moderate spacing is present between the lower end of the electric motor element 3 and a bottom of the closed vessel 2. A lower end of a crankshaft 20 is above an oil level 98 and the lower end of the crankshaft 20 is not submerged in lubricating oil 60. Therefore the lubricating oil 60 is not mixed with a step part 33 even if the crankshaft revolves and a mixing noise of the lubricating 60 is small.
