Improved muscle exercise device equipped with a pneumatic jack

摘要

The muscle exercise device of the invention comprises a take-off member (1) integral with the rod (2) of a pneumatic jack, the front chamber (6) of which is connected to a buffer reservoir (11) and to a source of compressed air (1), and the rear chamber (7) of which is connected to a source of compressed air (14, 18) by means of a pipe (17) equipped with at least one pusher (20) controlling either, in the active position, the pressing of the compressed air in the pipe (17), or, in the rest position, the free venting of the pipe (17). Characteristically, the pipe (17) is equipped with a means for timing the free venting, for example a flow regulator (24) equipped with a regulating means such as a centre punch screw. IMAGE
