Abstract

"AJUSTADOR DE FOLGA DE VáLVULA AUTOMáTICO, COMBINAçãO, MECANISMO DE OPERAçãO DE VáLVULA, E, MOTOR DE COMBUSTãO INTERNA". Um ajustador de folga de válvula automático, compreendendo um alojamento com rosca de parafuso interna (1); um membro de parafuso (3) com rosca de parafuso externa, que se estende no interior do alojamento; a rosca de parafuso (4) do membro de parafuso (3) tendo uma forma externa que é complementar à forma rosqueada da rosca interna (2) do alojamento e se ajusta na mesma com uma folga axial predeterminada, a rosca tendo forma trapezoidal, simétrica em seção transversal axial e exibindo mesma resistência friccional contra movimento em ambas direções axiais; sendo que os ângulos de flanco, ângulo de hélice e número de entradas da rosca de parafuso são selecionados para assegurar que o membro de parafuso irá girar e avançar axialmente para fora do alojamento somente sob a influência de uma força axial sobre sua extremidade dentro do alojamento; e a extremidade emergente (7) do membro de parafuso é adaptada para trabalhar em conjunção com um componente adjacente para receber dele uma resistência friccional à rotação."AUTOMATIC VALVE BLOCK ADJUSTER, COMBINATION, VALVE OPERATING MECHANISM, AND INTERNAL COMBUSTION ENGINE". An automatic valve slack adjuster comprising an internal screw thread housing (1); a screw member (3) with external screw thread extending inside the housing; the screw thread (4) of the screw member (3) having an outer shape that is complementary to the threaded shape of the housing's internal thread (2) and fits therewith a predetermined axial clearance, the thread having a symmetrical, trapezoidal shape in axial cross section and exhibiting same frictional resistance against movement in both axial directions; where the flank angles, propeller angle, and number of screw thread entries are selected to ensure that the screw member will rotate and advance axially out of the housing only under the influence of an axial force on its end within the housing. ; and the emergent end (7) of the screw member is adapted to work in conjunction with an adjacent component to receive frictional rotation resistance therefrom.
