Abstract:
1. An engine block assembly comprising: a stationary housing; a cylinder bank rotatably mounted to the housing about a central longitudinal axis, the cylinder bank having a plurality of cylinders therein radially distanced from and parallel to the central longitudinal axis, each cylinder having a cylinder wall, an intake port, an exhaust port, a valve assembly including one valve which simultaneously opens both the intake port and the exhaust port and which simultaneously closes both the intake port and the exhaust port, a piston moveable within the cylinder between an up position and a down position, and a connecting member having an inner end connected to the piston and an outer end; a thrust plate operatively connected to the outer ends of the connecting members, the thrust plate being rotatably mounted in a torque plane defined by the outer ends of the connecting members and which makes an oblique angle to a plane perpendicular to the central longitudinal axis, so that as the cylinder bank rotates the thrust plate sequentially guides each piston from the up position to the down position during a first portion of a rotation of the cylinder bank and then sequentially guides each piston from the down position to the up position during a second portion of the rotation of the cylinder bank; and a synchronizing member operatively connected to the cylinder bank and the thrust plate so that the cylinder bank and thrust plate rotate at the same speed.
