Abstract

Patente de Invenção: <B>"DISPOSITIVO PARA O ACIONAMENTO DE UMA VáLVULA PARA TROCA DE GáS DE UMA MáQUINA DE COMBUSTãO INTERNA DE êMBOLO DE CURSO"<D>. A invenção refere-se a um dispositivo para o acionamento de uma válvula para troca de uma máquina de combustão interna de êmbolo de curso, com um atuador eletromagnético que aciona essa válvula, o qual apresenta um imã de fechamento e um imã de abertura, entre os quais está disposta uma âncora, podendo se deslocar axialmente, a qual através de uma haste da âncora, disposta em uma guia, atua em conjunto com um sistema de mola sobre a haste da válvula, sendo que a haste da âncora é formada por um tubo, e sendo o dispositivo apresenta um elemento de compensação de jogo que está ligado com uma ligação de pressão para o abastecimento com meio de pressão, através da haste da âncora. A fim de criar um dispositivo para o acionamento de uma válvula para troca de gás de uma máquina de combustão interna de êmbolo de curso, o qual possua um peso mínimo com capacidade de carga suficiente, de acordo com a invenção é sugerido que a haste da âncora apresente áreas orientadas para carga com espessuras de parede diferentes.Invention Patent: <B> "DEVICE FOR THE ACTIVATION OF A VALVE FOR THE EXCHANGE OF GAS OF AN INTERNAL COMBUSTION MACHINE FOR COURSE PUMP" <D>. The invention relates to a device for activating a valve to change an internal piston stroke combustion machine, with an electromagnetic actuator that activates this valve, which has a closing magnet and an opening magnet, between which an anchor is disposed, being able to move axially, which through an anchor rod, arranged in a guide, acts in conjunction with a spring system on the valve stem, being that the anchor rod is formed by a tube, and the device having a compensation element of game that is connected with a pressure connection for supplying pressure medium, through the anchor rod. In order to create a device for the activation of a valve for gas exchange of a piston stroke internal combustion machine, which has a minimum weight with sufficient load capacity, according to the invention it is suggested that the piston rod anchor presents load-oriented areas with different wall thicknesses.
