The size of the steam cylinder is determined by the boilerpressure and the desired air pressure. As will be seen, thecompressor is entirely inclosed, but the working parts areeasily accessible; by a hinged door at the side, the connectingrods, cranks and main bearings are accessible, and all valvesare in the cylinder heads, each valve having its own cap ami apkil, 1899.
