Abstract
404,273. Pistons. OUBRIDGE, W. A., Parklands, Park Road, Coventry. June 9, 1932, No. 16258. [Class 122 (i).] In a light metal piston in which the gudgeon-pin bosses b are separated from the skirt a the latter is provided interiorly with one or more struts c<1> of oval ring form having a coefficient of expansion higher or lower than that of the piston. In the former case, the skirt is made oval with its major axis at right angles to the axis of the gudgeonpin bosses, Fig. 2, and the strut c<1> has its major axis parallel to the gudgeon pin axis; the skirt is thus caused to become circular when hot. When the strut has a coefficient of expansion less than that of the piston, it is forced under compression into the skirt with its major axis at right angles to the gudgeon pin axis ; the piston is thus deformed, but resumes the circular form when hot. In this case the piston may be turned oval before or after insertion of the strut, and may be slit circumferentially and /or axially. The strut may be split for convenience of assembly, and is either forced under compression into the skirt, or the piston may be cast about the strut while the latter is under initial stress. The strut may be placed immediately below and in contact with the gudgeon pin bosses to assist heat dissipation, and may be provided with radiating fins, webs or holes for this purpose. The strut may be in the form of a slotted oval disc, which may also act as an oil baffle.
