Problems solved by technology

Because induced losses in refrigerant fluid pressure adversely affect compressor efficiency
The increased size of the discharge muffler is an undesirable situation as it will also increase the size of the compressor
Also, due to space constraints within the compressor housing, the size of the discharge muffler cannot be increased by maintaining its current shape
When it is necessary to increase the size of the discharge muffler by keeping the size of the compressor constant, a problem arises that, inside the housing, the discharge muffler hits the crankshaft and the piston rod connected to the crankshaft

Embodiment Construction

[0037] In a cooling device such as a refrigerator, a refrigerant fluid is circulated by a hermetic compressor (1).

[0038] The hermetic compressor (1) comprises: a housing (2) carrying components therein; a motor (5) placed inside the housing (2); a cylinder (6) for pumping a refrigerant fluid; a piston (7), which acts in the cylinder (6) for compressing the refrigerant fluid into said cylinder (6) bore; the crankshaft (8), which transfers the motion transmitted from the motor (5); and, piston rod (9), which transfers the motion received from the crankshaft (8) to the piston (7) ( figure 2 ). Rotational motion in the motor (5) is delivered to the piston (7) by the crankshaft (8)-piston rod (9) mechanism and thus causes the piston (7) to reciprocate.

[0039] The hermetic compressor (1) also includes: a cylinder head (11), which is used to circulate refrigerant fluid, which is sucked in and pumped by the movement of the piston (7); a valve table (12), which is placed Betwee...

Abstract

The present invention relates to a hermetic compressor (1) that comprises a casing (2), a motor (5) disposed inside the casing (2), a cylinder (6) providing the refrigerant fluid to be pumped, a piston (7) functioning in the cylinder (6), providing the refrigerant fluid to be compressed into the cylinder (6) hole, a crankshaft (8) that transfers the motion delivered from the motor (5) and a piston rod (9) that transfers the motion received from the crankshaft (8) to the piston (7), a block (10) carries and / or bears the basic mechanical components like the cylinder (6), the piston (7), the crankshaft (8) and the piston rod (9), a suction muffler (3), disposed in the casing (2), providing the noise generated during suction of the refrigerant fluid to be attenuated and at least one exhaust muffler (4), disposed on the block (10), having a hollow, closed volume, providing the noise generated during pumping of the refrigerant fluid to be attenuated.

Description

technical field [0001] The invention relates to a compressor comprising a discharge silencer. Background technique [0002] In a reciprocating hermetic compressor, the pressure of the refrigerant fluid sucked in from the suction muffler is increased due to the reciprocating movement of the piston in the cylinder, and the high pressure fluid is delivered to the discharge muffler to be sent from there to refrigeration cycle. The pressure of the refrigerant fluid delivered to the discharge muffler is 5 to 20 times greater than the pressure of the fluid in the suction muffler, depending on the operating conditions of the cooling device. [0003] At high pressure, pressure fluctuations occur in the refrigerant fluid as it leaves the cylinder due to the reciprocating motion of the piston. Noise is generated due to these pressure fluctuations and refrigerant flow during fluid transfer into the discharge muffler. Discharge silencers are used to attenuate some of the frequency and...
