Conjunction of pre filtering applied in system of tyre brakes of heavy goods vehicles in general

摘要

Set of pre filtering applied in pneumatic system of brake of heavy vehicles in general and, more precisely, it is set of pre filtering (1) used in the pneumatic system of the brake (SP) heavy duty vehicles in general (not shown), such as, cargo trucks, buses, t. Rator, among others.The installation of a set of pre filtering (1) is made between the air compressor (CP) and valves (V) of the system {SP); said set of pre filtering (1) comprises shirt tubular shield (2) of primary filtering unit (3), which, in turn, provides the connection (3a) of conve Ncional element air dryer (EL).And the assembly in the longitudinal axis (E) between the shirt (2) and (3) comprises a camera unit passage (CS) of the contaminated air (AL) through the path (P) in the pre filtering (38) of the primary unit (3) and the element air dryer (EL) follows in purified air (A2) for the vu00e1lvu Las (V) of the system (SP); said path (P) of the contaminated air (AL) is obtained by the prediction of an opening ((2a) in the body (2b) of the shirt (2), which receives a connector (4a) of the flexible hose (4) of the air compressor (CP), and that said contaminated air (AL) when the passage in the pre filtering (38) of the primary unit (3) has a first cleaning according to the element of air dryer (EL) r A second cleaning ealiza composing the clean air (A2) which, in turn,Follow through duct (3C) of the primary unit (3) to the flexible hose (5) which leads the air clean (A2) to the valves (V).
