    Abstract: An engine comprises a housing and a combustion assembly carried by the housing. The combustion assembly comprises an annular bore defined by the housing, at least one combustion piston disposed within the annular bore, and a sealing mechanism configured to selectively seal the at least one combustion piston relative to at least one corresponding wall of the annular bore. The engine comprises at least one rotary valve configured to move between a first position within the annular bore to allow the at least one combustion piston to travel within the annular bore from a first location proximate to the at least one valve to a second location distal to the at least one rotary valve and a second position within the annular bore to define a combustion chamber relative to the at least one combustion piston at the second location.

    Abstract: A three stage vacuum pump has three stages of fixed scrolls and orbiting scrolls that operate simultaneously. A motor drives the second orbiting scroll within the third fixed scroll upon three equally spaced idlers. One idler then transmits rotation and torque into the second stage. The second orbiting scroll to has involutes upon both surfaces to engage the second fixed scroll inwardly and the first fixed scroll outwardly. The first fixed scroll has fins upon its back that extend into the atmosphere to transfer heat to air cool the invention. This pump also has a fan accelerating heat transfer. The pump operates the scrolls directly from a motor or from a motor and magnetic coupling so that the atmosphere does not infiltrate the pump.

The primary vacuum pump is an oil-free, positive displacement vacuum pump having multiple clearance seals between the inlet and the exhaust. The primary vacuum pump may be a scroll vacuum pump, and the secondary vacuum pump may be an oil-free diaphragm pump. The system may include a valve coupled to the exhaust of the primary vacuum pump and configured to couple the exhaust of the primary vacuum pump to an interpump exhaust in response to a selected condition, such as the pressure level at the exhaust of the primary vacuum pump.
