Abstract

Guarnizione per la testa cilindro di un compressore alternativo comprendente:un blocco cilindro (1) avente una cavità cilindrica alloggiante un pistone alternativo (2) e una estremità essendo aperta ad una faccia di estremità del blocco; una piastra valvolare (3) con una faccia anteriore e una faccia posteriore che è fissata contro dette faccia di estremità del blocco cilindro (1) e supportante una valvola di aspirazione (3a) e una valvola di scarico (3b); una guarnizione di cilindro tra detta faccia posteriore della piastra valvolare e detta faccia di estremità del blocco cilindro; un coperchio (5) di cilindro definente internamente una camera di aspirazione (5a) e una camera di scarico (5b) che sono aperte verso una faccia di estremità del coperchio del cilindro definita da un bordo (5e) circondante detta camera di aspirazione (5a) e una camera di scarico (5b) e essendo fissato contro la faccia anteriore della piastra valvolare (3); e una guarnizione (10) della testa disposta in modo tale da essere compressa tra il coperchio (5) del cilindro e la piastra valvolare (3). Secondo l'invenzione, una porzione (11) della guarnizione (10) della testa è fatta sporgere verso la parte interna del coperchio (5) del cilindro dal bordo circostante (5c), almeno nelle porzioni di esso che circondano la camera di scarico (5b), e sono maggiormente suscettibili di scorrimento...Gasket for the cylinder head of an reciprocating compressor comprising: a cylinder block (1) having a cylindrical cavity housing an reciprocating piston (2) and one end being open to an end face of the block; a valve plate (3) with a front face and a rear face which is fixed against said end face of the cylinder block (1) and supporting an intake valve (3a) and an exhaust valve (3b); a cylinder gasket between said rear face of the valve plate and said end face of the cylinder block; a cylinder cover (5) defining internally a suction chamber (5a) and an exhaust chamber (5b) which are open towards an end face of the cylinder cover defined by an edge (5e) surrounding said suction chamber (5a ) and an exhaust chamber (5b) and being fixed against the front face of the valve plate (3); and a head gasket (10) arranged so as to be compressed between the cylinder cover (5) and the valve plate (3). According to the invention, a portion (11) of the head gasket (10) is protruded towards the internal part of the cylinder cover (5) from the surrounding edge (5c), at least in the portions of it that surround the discharge chamber ( 5b), and are more susceptible to sliding ...
