Poppet valves in thistype are placed at an angle of 30 degrees to 45 degrees withthe center line of the cylinder, a construction made neces-sary by space restrictions on the cylinder heads. Compres-sors for other refrigerants are commonly of these samexypes, the main difference being that compressors tor carbondioxide systems are nearly always two-stage to producehigh compressions. The intermediate cooler pressures rangefrom 300 to 600 pounds per square inch. Horizontal steam OnO
