Abstract
A piston-rotation preventing structure for a variable displacement swash plate type compressor is disclosed. The piston-rotation preventing structure has a front housing and a cylinder block that constitute the housing of the compressor. The piston has a head portion and a jaw portion. The jaw portion is formed in the shape of an inverse U in such a way that a horizontal extension is horizontally extended from one side of the upper portion of the piston head portion and inside and outside jaws are respectively and vertically extended from both ends of the horizontal extension. The piston-rotation preventing structure comprises a pair of stopper grooves and a guide groove. The stopper grooves are extended along the upper surfaces of the horizontal extension and the piston head portion from the outer edge of the upper surface of the horizontal extension to a certain position on the upper surface of the piston head portion while being spaced apart from each other. The guide groove is longitudinally formed along the inner surface of the front housing over the stopper grooves to have the same width as the space between the stopper grooves.
