Synchronizer assembly for a scroll fluid device

A scroll fluid device comprising:

• at least one pair of axially extending spiral wraps each having first and second axially spaced end portions, said wraps being meshed and defining at least one chamber between them that moves radially between and inlet zone and an outlet zone when one wrap is orbited along a circular path about an orbit center relative to the other wrap:
• at least one pair of wrap support members, each of said wrap support members being secured to and supporting the first end portion of a respective wrap with the second end portion of each respective wrap defining a scroll flank, at least one of said wrap support members being adapted to be rotated so as to enable relative orbital motion of the wraps relative to each other about an orbit radius;
• and
• synchronizer means arranged to prevent relative rotation between said wraps while accommodating their relative orbital motion, said synchronizer means including a plurality of first synchronizer elements associated with the scroll flank of one of said wraps and a plurality of second synchronizer elements associated with the wrap support member of the other of said wraps, one of said plurality of first and second synchronizer elements comprising a first set of spaced, axially extending teeth and the other of said plurality of first and second synchronizer elements comprising a first set of spaced, axially extending grooves, said teeth and grooves being interdigitated, said synchronizer means further includes a plurality of third synchronizer elements carried by the scroll flank of said other wrap and a plurality of fourth synchronizer elements carried by the wrap support member of said one wrap, one of said plurality of third and fourth synchronizer elements comprising a second set of spaced, axially extending teeth and the other of said plurality of third and fourth synchronizer elements comprising a second set of spaced, axially extending grooves, said second sets of teeth and grooves being interdigitated.
