GAS EXHAUST DEVICE FOR TRANSPORTATION VEHICLE INTENDED FOR CONSTRUCTION WORKS Russian patent published in 2008 - IPC E01C19/48 

FIELD: transport.

SUBSTANCE: device to release two gases from transportation vehicle into ambient air, one gas featuring pressure pulsation of the first magnitude. The said device incorporates an elongated casing jointed to the vehicle and has the first inlet connected to the first gas source and the second inlet connected to the second gas source. It also has an outlet communicating, along the flowing medium, with ambient air and an inner mixing chamber, the said two inlets communicate, along the flowing medium, with the chamber so that two gases get inside the chamber. Two gases get combined inside the chamber in the casing to form a combined with pressure pulsation of smaller, second, magnitude and to release the said combined gas into ambient air. The casing can, preferably, comprises an outer tubular part with the first inlet and outlet and inner tubular part arranged inside the said outer part and including the second inlet and a set of holes.
