Abstract
A parallel adjustment assembly is provided for a scroll compressor which includes an orbiting scroll and a fixed scroll. The parallel adjustment assembly includes a housing and an eccentric guide shaft having opposed first and second ends. A step is defined by the eccentric guide shaft at an intermediate position along the shaft. A first bearing is fixedly mounted on the housing. The first bearing rotatably mounts the first end of the eccentric guide shaft. The eccentric guide shaft is moveable axially with respect to the first bearing. A biasing member biases the eccentric guide shaft in a direction toward the fixed scroll. A positioner, which is made integral with the eccentric guide shaft, precisely positions the eccentric guide shaft in the thrust direction.
