Abstract

"APARELHO DE OPERAçãO DE VáLVULA PARA UM MOTOR DE COMBUSTãO INTERNA, MOTOR E VEìCULO MOTORIZADO". Trata-se de um aparelho de operação de válvula para um motor de combustão interna, o qual inclui: um invólucro (2); um pistão alternante (1) que reside completamente dentro do invólucro (2), sendo que o pistão alternante (1) impele uma ou mais válvulas de fuso vertical (7) ; uma primeira passagem de suprimento de fluido e uma primeira passagem de drenagem de fluido, sendo que cada passagem é controlável para suprir ou drenar fluido para/de uma primeira extremidade do alternante (16) ; uma segunda passagem de suprimento de fluido e uma segunda passagem de drenagem de fluido, sendo que cada passagem é controlável para suprir ou drenar fluido para/ de uma segunda extremidade do pistão alternante (17); sendo que o dito pistão alternante (1), em uso, é impelido entre uma primeira posição e uma segunda posição mediante o controle do dito fluido nas ditas passagens de suprimento e drenagem, desse modo operando uma ou mais das ditas válvulas de fuso vertical (7), e em que um conector (9) passa através de uma abertura (14) no dito invólucro (2) para conectar o dito pistão alternante (1) uma ou mais ditas válvulas de fuso vertical (7), com o dito pistão alternante (1) em cooperação com uma parede interna do invólucro formando uma vedação para impedir o egresso substancial de fluido do invólucro (2) através da dita abertura (14)."VALVE OPERATING APPLIANCE FOR INTERNAL COMBUSTION ENGINE, ENGINE AND MOTOR VEHICLE". It is a valve operating apparatus for an internal combustion engine which includes: a housing (2); an alternating piston (1) which resides completely within the housing (2), the alternating piston (1) driving one or more vertical screw valves (7); a first fluid supply passage and a first fluid drainage passage, each passage being controllable to supply or drain fluid to / from a first end of the alternate (16); a second fluid supply passage and a second fluid drainage passage, each passage being controllable to supply or drain fluid to / from a second end of the alternating piston (17); wherein said reciprocating piston (1), in use, is propelled between a first position and a second position by controlling said fluid in said supply and drainage passages, thereby operating one or more of said vertical screw valves ( 7), and wherein a connector (9) passes through an opening (14) in said housing (2) for connecting said reciprocating piston (1) to one or more said vertical screw valves (7) with said piston alternating (1) in cooperation with an inner wall of the housing forming a seal to prevent substantial leakage of fluid from the housing (2) through said opening (14).
