Abstract
Disclosed herein is a muffler of a linear compressor. In the present invention, a center of an entry pipe of the muffler is in line with that of an inhale port of a piston. Therefore, a flow loss occurred when fluid is inhaled into the inhale port from the entry pipe can be reduced, and inhale efficiency can be improved. Furthermore, the plurality of inhale ports is eccentrically disposed in a front of the piston, and each center of the plurality of entry pipes is formed to be in line with that of the inhale ports. Not only the center but also the number of the inhale port and the entry pipe are agreed, on this account, the flow loss can be decreased and the inhale volume can be increased.
Claims11
A muffler of a linear compressor, comprising:
- a piston having an inhale port in front;
- an inhale valve for opening and closing the inhale port equipped in the front of the piston and placed close to the inhale port;
- a muffler body mounted in a rear of the piston;
- and
- an entry pipe extended from the muffler body to be inserted into the piston,
- wherein a center of the entry pipe is formed to be in line with a center of the inhale port, and
- the inhale port is formed at the piston close to the inhale valve, and
- wherein a diameter of the entry pipe corresponds to a diameter of the inhale port.
A muffler of a linear compressor, comprising:
- a hermetic casing;
