Abstract:
1. A reciprocating piston machine of the single-cam type, the machine comprising: at least one radial odd-lobe cam fixed to a camshaft that is rotatably mounted in a camcase; a pair of opposed cam followers disposed about the odd-lobe cam, the pair of cam followers operatively engaged on opposite sides of the track surface of the cam; a follower arm link extending across the camshaft axis, the arm link functionally connected to and providing spaced apart support for the pair of cam followers; a pair of generally laterally-extending link follower arms with each link follower arm having a pivot end and a follower end, the pair of link follower arms pivotally connected at their follower ends to the opposite ends of the follower arm link; a pair of fixed pivot pins pivotally connecting the link follower arm pivot ends to the camcase, wherein as the cam rotates, the pair of link follower arms pivotally support the follower arm link and the cam followers; at least one cylinder and operatively associated piston mounted for reciprocation within the cylinder, at least one cylinder attached to the camcase, each corresponding piston connected to a piston rod; and at least one end of the follower arm link functionally connected to a corresponding piston rod.
