Abstract
A scroll-type hydraulic machine having a first stationary scroll with a first scroll wrap, a first orbiting scroll with a second scroll wrap on one surface thereof interleaved with the first scroll wrap, a first orbiting scroll shaft on the other surface of the first orbiting scroll, a second stationary scroll having a third scroll wrap, a second orbiting scroll having a fourth scroll wrap on one surface interleaved with the third scroll wrap, a second orbiting scroll shaft provided on the other surface of the second orbiting scroll, and a crank mechanism. The crank mechanism includes a rotatably driven crankshaft having an eccentric through-hole extending lengthwise therethrough, an eccentric shaft rotatably supported by bearings in the eccentric through-hole, and first and second eccentric ring mechanisms. Each eccentric ring mechanism is provided at one end of the eccentric shaft and is rotatable with respect thereto. The orbiting scroll shafts are driven in an orbital pattern through the respective eccentric ring mechanisms.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
