Abstract:
A reciprocating compressor may include a discharge muffler that attenuates discharge noise of a discharge gas discharged after being compressed in a cylinder of a compression unit, and two or more discharge hoses coupled to the discharge muffler and that discharges the discharge gas outside of the compression unit through a discharge pipe. As the reciprocating compressor has two or more discharge hoses that connect the discharge muffler and the discharge pipe, while a rigidity is reduced by reducing an inner diameter of the discharge hose, clogging of the discharge gas during high-speed operation may be suppressed or prevented and pulsation may be effectively reduced.

Abstract:
A reciprocating compressor according to an embodiment of the present disclosure includes a crankshaft including a shaft portion, an eccentric mass portion, and a pin portion, and an oil groove positioned on an outer surface of the pin portion is configured to supply an oil to a pressurized portion of a bearing immediately before entering a section in which a gas load increases. For example, the oil groove can supply the oil to the bearing in a stroke section immediately before a crank angle reaches 270°. According to the above configuration, the oil is supplied to the pressurized portion of the bearing formed by the pin portion of the crankshaft and a connecting rod immediately before entering a stroke section subjected to a high load. Accordingly, lubrication by the oil can be smoothly performed in the stroke section subjected to the high load, and oil shortage can be improved even if the oil groove adopts a structure in which the bearing is open at the top and bottom.

A display device according to one embodiment includes a first display, a second display disposed at a front side of the first display with a predetermined distance therebetween, and arranged in parallel to the first display, and a controller configured to control the first display and the second display to alternately output a specific graphic object to realize an output of a three-dimensional image.
Abstract:
A reciprocating compressor may include a ball bearing positioned between a thrust surface of a cylinder block and a thrust surface of a crankshaft. The ball bearing may include a ball cage in a ring shape, a plurality of balls rotatably coupled to the ball cage, at least one washer positioned at least one of between the thrust surface of the cylinder block and the plurality of balls and between the thrust surface of the crankshaft and the plurality of balls, and a rotation preventing portion that limits rotation of the washer with respect to the corresponding thrust surface. According to a reciprocating compressor having the rotation preventing portion, as relative rotation of the washer with respect to the thrust surface of the cylinder block and/or the thrust surface of the crankshaft is restrained even if a rotational force higher than a viscous force acting on the washer is applied because a viscosity of oil is lowered, it is possible to eliminate the problem of deterioration of reliability and performance of the compressor.
