Abstract (en)
[origin: EP1319838A1] A highly reliable scroll compressor with an improved oil injection mechanism having a particular composition in a particular position in a scroll compression element is disclosed. The oil injection mechanism for injecting and supplying a lubricant is provided in the vicinity of an intake position where a refrigerant gas is introduced from outside an hermetic housing into the scroll compression element via an intake pipe. The oil injection mechanism is fixed to a support frame being composed of an oil nozzle for injecting the lubricant through an oil feed passage and a valve that opens/closes an oil feed passage inlet of the oil nozzle by utilizing the elasticity of a spring. The oil injection mechanism may be fixed at other location than the support frame; it may be secured, for example, to an stationary scroll. <IMAGE>
