Abstract
The invention relates to an inner burner () for electric arc wire spraying of hollow spaces, particularly cylinder bearing surfaces (), comprising two meltable electrodes which are supplied in two feed channels () to a discharge nozzle () of the inner burner (). The two electrodes are connected to two sliding contacts () for electrical energy transmission. According to the invention, the two sliding contacts () are displaceably mounted in the axial direction () and are each connected to a guide element () which is also displaceably mounted in the axial direction (). The respective guide element () is axially pretensioned via at least one associated spring () and thereby presses the sliding contact () against the electrode, wherein the feed channels (), the sliding contacts () and the guide elements () are arranged parallel to one another in the spraying head ().
