摘要： The disclosure provides an oil tubing installation assembly and a scroll compressor adopting the same. The oil tubing installation assembly is adapted to be installed into a shell in a vertical direction and includes: a housing on which a vertical oil tubing installation surface and an oil hole located in the oil tubing installation surface are provided; a clip adapted to be installed on the oil tubing installation surface and into the shell along with the housing; and an oil tubing assembly adapted to be installed into the clip in a vertical direction after the housing and the clip have been installed into the shell. The oil tubing assembly includes an oil tubing body and a cuboid-shaped installation block. A through hole is provided in the installation block and the through hole is configured to have a first orifice on the front surface of the installation block and a second orifice on the rear surface of the installation block. The upper end of the oil tubing body is connected to the first orifice. The second orifice is aligned with and fitted to the oil hole after the installation block is installed in place in the clip. In this way, the long oil tubing can be easily installed manually in place even after the housing has been pressed into the shell.

摘要： A flow regulating valve and a compressor with the flow regulating valve are disclosed. The flow regulating valve includes: a valve seat in which a passage is formed to allow fluid to enter; a guide member protruded outwards from the valve seat; a piston which is disposed on the outside of the valve seat, forms a fluid inlet with the valve seat, and is capable of being reciprocated along the guide member; and a biasing member biasing the piston in a direction away from the valve seat. A force exerted by the incoming fluid on the piston is opposite in direction to a biasing force exerted by the biasing member on the piston. The piston is able to be moved to different positions under the action of different forces to form fluid inlets of different widths with the valve seat, thereby controlling the mass flow rate of the incoming fluid (especially liquid). With the technical solutions of the present invention, the flow rate of the fluid entering the compressor can be effectively adjusted with a simple structure and low cost.
