Patent
Capacity modulated scroll machine
TL;DR: In this paper, the capacity of a scroll-type machine is modulated by relative axial movement between the scroll members so as to form a leakage path across the wrap tips and opposed end plates.
Patent
Compressor pulse width modulation
TL;DR: In this article, the capacity modulation system of a scroll compressor is described, where the non-orbiting scroll member moves into engagement with the orbiting scroll when the chamber is placed in communication with the discharge chamber.
Patent
Scroll machine with discus discharge valve
TL;DR: In this article, a scroll compressor includes a discharge valve assembly for blocking compressed refrigerant flow from the discharge chamber through the scroll members, which results in an increased performance for the scroll compressor by minimizing the recompression volume due to the configuration of the value assembly and thus the elimination of reverse rotation at shut down.
