Claim:
A rolling valve for use in an internal combustion engine, said engine including a cylinder containing an inlet and an outlet port, comprising: (a) a rolling plate having a top, a bottom, a center and a central axis of rotation passing though said center of said plate and said axis being generally orthogonal with the top and bottom of said plate, (b) connecting means for connecting said rolling plate to said engine to cause said plate to revolve at a speed which is a selected function of the engine speed, (c) a rolling plate port passing from the top to the bottom of said rolling plate, (d) a rolling plate input connecting means having a first and a second end, said first end being connected to a source and said second end being in sliding contact with the top of said rolling plate and positioned to be over and cover said rolling plate port at least once during each revolution of said plate to accept a gas from said source and deliver it to said rolling plate port, and (e) a rolling plate output connection means having a first and a second end, said first end being connected to a receiver and said second end being in sliding contact with the bottom of said rolling plate and positioned to be directly below said second end of said rolling plate input connection means and to be also under and cover said rolling plate port at the same time that said rolling plate input connecting means is above said rolling plate port during each revolution to transmit a gas from said source to said receiver at a precise time in the engine cycle.
