<p>The ventilator is for brake actuators, having a screw for hand braking, which acts together with a sleeve in the actuator spring is in connection with the ambient air via a filter and a channel system. The channel system has a ring chamber (8), extending around the sleeve (7). The chamber contains the filter (9), and is in connection with the ambient air via spiral channels and passages (12-15). The inner channels and passages are staggered to the radial outer ones. The ring chamber is connected to the support chamber (14) of the activator spring (M), via one or more bores (10) in the sleeve, and arring passage (11). The ring chamber is limited to the outside by a housing (16, 17) acting with the sleeve and the outer base (6) of the actuator, which has a recess to accommodate the ventilator.</p> |
