DEFINITION
Classification: 123/204
With compression volume means in uninterrupted communication with expansion volume means:
(under subclass 200) Apparatus wherein the piston structure cooperates with one or more other elements or with another piston structure or with the cylinder structure such that an unobstructed passageway always exists between the volume in which the air or combustible material is compressed and the volume in which the combustible material is burned.
(1) Note. This subclass includes engines operating on the Brayton (constant pressure) cycle.
