AUTOMATICALLY CONTROLLED APPARATUS FOR DRAINING THE CONDENSATE FROM THE PRESSURIZED GAS RESERVOIRS PARTICULARLY FORM THE AIR RECEIVERS OF THE INDUSTRIAL VEHICLES AND VALVE

摘要

Automatically controlled apparatus for the condensate drainage from the pressurized gas reservoirs (11A-11F), particularly from the air receivers of the industrial vehicles, including a pneumatic member (40) designed for being automatically operated whenever the motor of the vehicle is stopped, a control system (30-35) connected to said pneumatic member, and a valve device (10A-10F) provided for each reservoir (11A-11F) from which the condensate has to be drained, each valve device (10A-10F) being operated by said control system in order to pass from the closed to the opened position and viceversa whenever the pneumatic member is operated, and including: a finned (262) cylindrical body (210); a frustum-conical drainage valve member (223); a valve stem (216) connected to and controlling said drainage valve member; and a cylindrical spline head (224) integral with the frustum-conical drainage valve member and promoting a smooth and noiseless operation of the valve device.
