Improvements in cold air or like refrigerating apparatus
Реферат: 187,994. Soc. Italiana E. Breda. Oct. 29, 1921, [Convention date]. Refrigerating, cold-air and like machines for.- Air or other gas from an enclosed space to be cooled is admitted through a branch b and valve c to a compressor cylinder d and delivered through a valve e and pipe f to a coil g exposed to a current of cooling-air produced by a fan h. The. compressed cooled gas passes to an expansion cylinder o from which it passes through a pipe p to the space to be cooled, returning again to the compressor. The compression and expansion pistons are arranged as one member t working in cylinders of different diameters. The valves c, e of the compressor are self-acting, while the valves of the expansion cylinder are actuated from cams on the main crank shaft. This shaft may be driven through gearing n, m from a shaft i driven by a pulley or by a directly coupled motor. The fan h is driven by gearing from the shaft i. The Specification, as open to inspection under Sect. 91 (3) (a) comprises also apparatus wherein separate compression and expansion cylinders are employed. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 2064/75. 3340/77, [Class 78, Lifting &c.], 605/82, 673/82, 4051/82, 15138/86 and 19391/95.
