Abstract
An orbiting rotary compressor assembly having a compression mechanism disposed in a housing and including relatively moving fixed and orbiting compression members including extending portions having surfaces engaged with each other and between which a compression chamber is located. The orbiting member has a centrally-located hub which moves eccentrically relative to the axis of rotation of a drive shaft in driving engagement with the hub. A vane operatively engages the fixed member extending portion and the orbiting member extending portion, and partially defines the compression chamber. An Oldham coupling is disposed about and is in engagement with the hub, and is in engagement with the fixed compression member, rotation of the orbiting compression member being prevented by the Oldham coupling.
Claims20
An orbiting rotary compressor assembly comprising:
- a compressor housing;
- a compression mechanism disposed in said housing and including relatively moving fixed and orbiting compression members, said compression members having extending portions having surfaces engaged with each other and between which a compression chamber is located, said orbiting member further having a centrally-located hub;
- a rotating drive shaft having an axis of rotation and in driving engagement with said orbiting compression member hub, said hub having eccentric movement relative to said axis of rotation;
- a vane operatively engaging said fixed member extending portion and said orbiting member extending portion, said compression chamber being partially defined by said vane;
- and
- an Oldham coupling disposed about and in engagement with said hub, said Oldham coupling also being in engagement with said fixed compression member, rotation of said orbiting compression member being prevented by said Oldham coupling.
An orbiting rotary compressor assembly comprising:
- a compressor housing;
- a compression mechanism disposed in said housing and including relatively moving fixed and orbiting compression members, and an outboard bearing fixed to said fixed compression member and which supports said orbiting compression member, said compression members each having a base from which an extending portion extends, said fixed and orbiting compression member extending portions having surfaces engaged with each other and between which a compression chamber is located, said orbiting member further having a centrally-located hub extending from its said base, said hub and said fixed compression member being a first pair of relatively moving elements, said outboard bearing and said orbiting compression member base being a second pair of relatively moving elements;
- a rotating drive shaft having an axis of rotation and in driving engagement with said orbiting compression member hub, said hub having eccentric movement relative to said axis of rotation;
- a vane operatively engaging said fixed member extending portion and said orbiting member extending portion, said compression chamber being partially defined by said vane;
- and
- an Oldham coupling reciprocatively engaged with each relatively moving element of one of said first and second pairs of relatively moving elements, rotation of said orbiting compression member being prevented by said Oldham coupling.
