ABSTRACT:
A hand held, spring actuated, vacuum desoldering implement is disclosed having a tubular body and a forward end cap portion thereof. The end cap has a central bore for removeably retaining a small, tubular Teflon nozzle element. The rear end of the nozzle element is formed with an increased diameter retainer collar portion to limit its forward and outward disposition within the end cap bore. The nozzle element is provided with an annular, O-ring retaining groove disposed axially contiguously to the forward end of the end cap; and an O-ring is disposed therein to retain in cooperation with its retainer collar, the nozzle element within the end cap portion. The outer diameter of the nozzle is less than that of the end cap bore whereby the nozzle element is provided with a nutational freedom of movement about its rear retaining collar connection with the end cap, this motion being cushioned and limited by compressing the O-ring laterally. A rearward, cushioned displacement of the nozzle element is also permitted by the O-ring. It is to be noted that the axial and nutational displacements are permitted while the O-ring maintains a vacuum seal between the nozzle element and the end cap.
