Abstract
A radially compliant scroll compressor includes a fixed scroll, an orbiting scroll operatively connected to the fixed scroll, a synchronizer and at least one linkage member operatively connected to the orbiting scroll and the synchronizer. The at least one linkage member includes an orbiting crank handle operatively disposed on the linkage member, a crankpin operatively disposed through said synchronizer and extending into the crank handle and a damping member disposed on the crankpin between the synchronizer and the crank handle.
Claims14
A scroll compressor comprising:
- a fixed scroll;
- an orbiting scroll operatively connected to said fixed scroll;
- a synchronizer;
- and
- at least one linkage member operatively connected to said orbiting scroll and said synchronizer, said at least one linkage member including:
- an orbiting crank handle operatively disposed on said linkage member;
- a crankpin operatively disposed through said synchronizer and extending into said crank handle;
- and
- a damping member operatively disposed on said crankpin, between said synchronizer and said crank handle.
An oxygen generating system, comprising:
- a housing having an inlet configured to receive a feed gas;
- a scroll compressor for compressing said feed gas;
- at lease one sieve bed within said housing, said sieve bed including a nitrogen- adsorbing material configured to adsorb at least a portion of a nitrogen gas from said compressed feed gas introduced thereto to generate an oxygen enriched gas;
- said scroll compressor including a fixed scroll;
- an orbiting scroll operatively connected to said fixed scroll;
- a synchronizer;
- and
- at least one linkage member operatively connected to said orbiting scroll, and said synchronizer, said at least one linkage member including:
- an orbiting crank handle operatively disposed on said linkage member;
- a crankpin operatively disposed through said synchronizer and extending into said crank handle;
- and
- a damping member operatively disposed on said crankpin, between said synchronizer and said crank handle.
