Jones, C

This patent describes a rotary internal combustion engine having a trochoid rotor housing section and having a group of cooling passages extending through a top-dead-center (TDC) region. The engine is characterized by: at least one passage of the group following a curved path which extends through a first hotter portion of the TDC region, by at least one further passage of the group following a substantially uncurved path through a second cooler portion of the TDC region, and by a fluid restriction for restricting fluid flow through the at least one further passage to balance coolant flow between the passages.
