Abstract
Un motocompressore (1), in particolare per un refrigeratore, comprende una testa di cilindro (10) fissata su un corpo di cilindro (5), tra tale testa (10) e corpo di cilindro (5) essendo interposta una piastra (11), a cui sono associate usuali valvole (14, 15) poste su condotti di aspirazione (12) e mandata (13).Secondo l'innovazione, la testa di cilindro (10) è realizzata in almeno due porzioni (21, 22) cave, accoppiate tra loro, almeno una di tali porzioni (22) essendo realizzata in materiale avente bassi valori di conduttività termica. Le due porzioni (21, 22) della testa di cilindro (10) sono fisicamente separate tra loro: una di esse (22) presenta almeno una cavità fungente da cavità di aspirazione, l'altra porzione presenta invece almeno una cavità fungente da cavità di scarico.A motor-compressor (1), in particular for a chiller, comprises a cylinder head (10) fixed on a cylinder body (5), between this head (10) and cylinder body (5) being interposed a plate (11) , which are associated with usual valves (14, 15) placed on suction (12) and delivery (13) ducts. According to the innovation, the cylinder head (10) is made of at least two hollow portions (21, 22) coupled together, at least one of these portions (22) being made of material having low thermal conductivity values. The two portions (21, 22) of the cylinder head (10) are physically separated from each other: one of them (22) has at least one cavity acting as a suction cavity, the other portion instead has at least one cavity acting as a cavity of drain.
