Abstract
A compressor may comprise: a first fluid channel provided to communicate with an oil supply fluid channel so as to allow oil to flow therethrough; a second fluid channel provided to extend from the first fluid channel so as to allow the oil to flow to the outside of a case; a third fluid channel extending from the second fluid channel and provided outside the case; and a main fluid channel extending from the third fluid channel and provided through a fixed scroll or a main frame. Accordingly, the oil is supplied to a compression part by passing along the outside of the case, so that oil can be effectively supplied when a high-pressure operation is performed. Moreover, the present invention may not have a facility such as a pressure reduction pin, so that oil can be effectively supplied when a low-pressure operation is performed.
