Perforateur comportant un carter (11) ayant un mécanisme de frappe pneumatique (17) logé dans le carter (11) et présentant un tube de guidage (12) positionné de manière à tourner par rapport au carter (11) et mobile axialement en fonction d'une pression d'outil sur la zone concernée, ayant au moins une ouverture de ventilation (36) disposée dans le tube de guidage (12) et ouverte lorsque le mécanisme de frappe (17) est au point mort afin d'aérer un coussin d'air (22), mais qui peut être recouverte d'un organe de fermeture (37) après une course axiale du tube de guidage (12),
    caractérisé en ce que
    l'organe de fermeture (37) est par rapport au carter (11) solidaire en rotation dans le sens de rotation du tube de guidage (12) et porte une denture de blocage (67) pour le blocage fixe en rotation du tube de guidage (12).
  2. Perforateur selon la revendication 1,
    caractérisé en ce que
    l'organe de fermeture (37) est constitué d'un manchon multifonctionnel (25) qui, en tant que composant séparé, entoure le tube de guidage (12) et est introduit ou inséré sous pression dans le carter (11) de manière fixe en rotation et axialement.
  3. Perforateur selon la revendication 2,
    caractérisé en ce que

    caractérisé en ce que
    la denture de blocage (67) peut être engagée dans une denture (69) sur une gaine de commutation (68) mobile dans le sens axial, et solidaire en rotation du tube de guidage (12).
  5. Perforateur selon la revendication 4,
    caractérisé en ce que
    la denture de blocage (67) est constituée de dents (421, 422) en saillie dans le sens radial à la périphérie extérieure du manchon multifonctionnel (25).
