Abstract: Disclosed is a hermetic compressor equipped with a suction muffler comprising; a muffling space having two rooms; a communication space to communicate these two rooms with each other; a first communication passage to communicate a movable valve with the muffling space and extending to an opening to the muffling space; and a second communication passage to communicate a enclosed container with the muffling space and extending to an opening to the muffling space. The openings to the muffling space from the first and the second communication passages are disposed in one of the two rooms, and the other room of the two rooms forms a resonance muffler whose resonance frequency matches with an cavity resonance frequency of the enclosed container. The configuration can provide the hermetic compressor with a reduced noise emission and a high compression efficiency.

Abstract: In the structure of an air pump with low noise, the diameters of an inlet and an outlet in the main body of the pump are reduced (such as 1.3 mm) to be smaller than that normally used (such as 2.0 mm), and the areas of air control films used are coincidently reduced, the cross-sectional area of a noise-silencing channel is also set in coincidence with the areas of the inlet and the outlet. Thereby, sounds generated by repeated beating of the air control films on the inlet and the outlet against the inner walls of the main body of the air pump can be reduced; thus noise in operation of such an air pump can be reduced too.

Abstract: An air compressor, air storage, and high pressure cleaning machine structure comprised of an air compression and air storage mechanism and a high pressure cleaning mechanism that are powered by a single electric motor in an integrated arrangement, wherein the two protruding ends of a main shaft in the electric motor are inserted into a unidirectional bearing, following which they are respectively coupled to the air compression, air storage mechanism and the high pressure cleaning mechanism. The two mechanisms are installed on a foldable two-section wheeled frame and the user controls the electric motor with a toggle switch to selectively deviate the main shaft in the electric motor towards one of the two unidirectional bearings such that said electric motor drives either the air compression and air storage mechanism or the high pressure cleaning mechanism. As such, the two-in-one arrangement effectively reduces space occupancy and facilitates operating convenience.

Abstract: A reciprocating compressor has a pair of discharge mufflers disposed on a lower portion of a cylinder block, a first and a second refrigerant channels for intercommunicating the pair of discharge mufflers with a refrigerant discharge chamber of a cylinder head, a pair of muffler covers for sealing the pair of discharge mufflers, respectively, a connecting pipe for connecting the pair of muffler covers with each other, and a refrigerant discharge pipe connected to either one of the pair of muffler covers that is intercommunicated with the second refrigerant channel. The first and the second refrigerant channels have refrigerant inflow sides connected to the refrigerant discharge chamber, and refrigerant outflow sides having a cross-sectional area smaller than the cross-sectional area of the refrigerant inflow sides. The relationship between the cross-sectional areas of the refrigerant outflow side of the first refrigerant channel, the refrigerant outflow side of the second refrigerant channel, and the connecting pipe, is varied according to an exhaust air volume of the compressor. In the reciprocating compressor, by increasing flow resistance of the refrigerant channels, discharge pulsation of refrigerant can be reduced.

Abstract: A compressor system having a first compartment for housing relatively quietly operating equipment, and a second compartment for housing relatively noisy operating equipment. The second compartment is substantially closed off from the surrounding atmosphere to reduce the amount of noise that can be heard outside the compressor system on account of the noisy equipment operating within the compressor system housing. The second compartment includes a small air inlet opening and a small air outlet opening to allow enough air to flow through the second compartment to cool the equipment housed therein. The small openings reduce the amount of air-born noise which is released to the outside environment. The compressor system also has an air intake directing device for directing an appropriate amount of air into the second compartment to cool the noise generating machinery located within the second compartment, and for directing an appropriate amount of air to an air inlet opening of a compressor, thereby more efficiently using the air drawn into the compressor system housing.
