TLDR
In this paper, an oil pump assembly and a linear compressor comprising the same was presented, where the elastic reset piece was arranged between the cylinder body and the piston, and the reset piece is either in the first cavity body, or in the second cavity body.Abstract:
The invention provides an oil pump assembly and a linear compressor comprising the same. The oil pump assembly comprises a cylinder body with an inner cavity, a piston and an elastic reset piece, wherein the piston is movably arranged in the inner cavity and divides the inner cavity into a first cavity body and a second cavity body; the cylinder body is provided with an oil inlet hole and an oil outlet hole which both communicate with the first cavity body; the elastic reset piece is arranged between the cylinder body and the piston; the elastic reset piece is arranged in the first cavity body, and the second cavity body is an empty cavity; or the elastic reset piece is arranged in the second cavity body, and the first cavity body is an empty cavity. According to the technical scheme, the problems that an oil pump of a linear compressor is complex in assembly process and high in cost in the prior art are solved.read more
