Abstract:
A scroll compressor comprising:a non-orbiting scroll having a base and a scroll wrap extending from said base;an orbiting scroll having a base and a scroll wrap extending from said base in a direction toward said base of said non-orbiting scroll, said wraps of said non-orbiting and orbiting scrolls interfitting to define compression chambers;a crank shaft having an eccentric for driving said orbiting scroll;a slider block positioned between said eccentric and said orbiting scroll, said slider block allowing said orbiting scroll to change an orbit radius and allow said orbiting scroll wrap to move into contact with said non-orbiting scroll wrap; andstructure on said slider block and said eccentric to allow said orbiting scroll to move into contact with said non-orbiting scroll when said crank shaft is rotated in a first direction, but to prevent said orbiting scroll from moving into contact with said non-orbiting scroll if said crank shaft is rotated in a second direction opposed to said first direction under at least some operational speeds, said structure including an arc interface between said slider block and said eccentric which is in contact when said orbiting scroll is rotated in said first direction.
