摘要
the vibrator has a lower closure cap (29) for the housing (23) which is permanently welded rather than screwed. The housing upper part is permanently stuck on. The housing need not be hardened and requires no rubber closure cap but is completely encased with a high wear resistant plastics elastomer.
