Abstract
a presente invenção se refere a um motor de combustão compreendendo uma primeira válvula de motor controlável (8) disposta para seletivamente abrir/fechar uma câmara de combustão (7) de referido motor de combustão, uma cabeça de cilindro (6) que é adjacente para a câmara de combustão (7), e que é disposta para guiar uma haste de válvula (38) da válvula de motor (8), a válvula de motor (8) sendo axialmente deslocável em relação para referida cabeça de cilindro (6) entre uma primeira posição na qual a câmara de combustão (7) está fechada e uma segunda posição na qual a câmara de combustão (7) está totalmente aberta, e um retentor de mola de válvula (39) que é conectado para referida haste de válvula (38). em concordância com a presente invenção, o motor de combustão é caracterizado pelo fato de que o retentor de mola de válvula (39) parcialmente delimita um volume de mola de gás (48), que está em comunicação de fluido com um volume de gás adjacente (49) por intermédio de um orifício (50) quando a válvula de motor (8) está na posição fechada, e que é separado a partir do volume de gás adjacente (49) quando a válvula de motor (8) está em sua posição aberta, referido orifício (50) sendo aberto durante pelo menos 25 porcento do curso de êmbolo máximo da válvula de motor (8) e sendo fechado devido para um deslocamento da válvula de motor (8).
