Abstract
An improved slider block for a scroll compressor has a bore including two spaced circular portions centered on a common axis. A recess is formed into one of the curved portions to provide additional clearance for movement of an eccentric pin. The recess allows the eccentric pin to move within the bore, as the relative position of the slider block and the eccentric pin move and change during operation of the scroll compressor. In a further embodiment, chamfers are formed at circumferential ends of a non-drive flat surface to merge that non-drive flat surface into the circular portions. This will ensure the slider block is properly positioned on smaller eccentric pins.
