Abstract

484,196. Combustion - product power plant. MAINA, J. Sept. 2, 1936, No. 24024. [Class 7 (i)] [Also in Groups XII and XXVIII] A charge of air after being compressed to a high degree in a, compressor a is transferred to a generator of combustion products under pressure by positively actuated means comprising two opposed pistons c, d, the charge being delivered into the space between the pistons and rapidly expelled from the space through a port h leading to the generator. As shown, the pistons move in a cylinder b at right-angles to the cylinder a. A communicating port e between the cylinders is utilized for the inlet of air to the cylinder a through an inlet port g and an annular recess f around the piston d, and for the transfer of compressed air from the cylinder d to the space between the pistons c, d. The cranks from which the pistons c, d are driven are so arranged relatively to each other that those pistons control the inlet and outlet ports g, e, h at suitable times, and the pistons gradually approach each other during the final stage of delivery through the port h to the generator, in order to compress the charge further and to expel it completely. The transfer of combustion products from the generator through a passage h<1> to a power cylinder B is effected by opposed pistons c<1>, d<1> similar to the pistons c, d but without a recess such as f in the piston d<1>. The generator may be of the form described in Specification 447,266.
