Abstract (en)

[origin: EP2693057A2] A scroll type device for operating on a fluid provided thereto that includes, as a unit, a housing (102) with two interleaved scroll plates (104,106) that are installed within such housing (102) and that are operably movable relative to one another in an eccentric orbit, with such scroll plates (104,106) including interleaved spiral projections on facing sides thereof, each of which spiral projections includes first and second portions, with the first spiral portion forming an inner involute spiral that spirals outwardly from the center in one spiral direction to an intermediate spiral point (142) located intermediately between the center and the outer limit of the scroll plate and a second spiral portion forming an outer involute spiral wrap that spirals outwardly from the intermediate spiral point (142) in the opposite, or counter, direction from that of the inner involute spiral to an outer spiral point (144) near the outer limit of the scroll plate, one of which portions will operate for expansion and the other of which portions will operate for compression as the unit operates in a given normal direction of movement.
