The valve of the correction of level for the pneumatic suspension of anti, in particular of utility, 2004.

摘要

The invention relates to a valve of the correction of the level for a pneumatic suspension, the body of which contains, in a bore, a push-button of the valve (23) which can be moved as a function of the load of the vehicle, in order to act on a valve (17, 19) connecting the pneumatic springs to a source of compressed air or to the atmosphere. The grooves, which are diametrically opposed and extend in the longitudinal direction in the wall of the bore, from the valve (17, 19) to the - beyond the mouth of the lateral holes (37, 39) of the body, leading to the pneumatic springs, without communicating with the holes. The push rod (23) has a widened part of the dispenser (41) of a diameter substantially equal to the inside diameter of the bore and with the edges of the distribution of the upper and lower, as well as an external annular groove (47), the grooves with the transverse bores (37, 39) when the delivery part (41) covers the latter, a constriction in the axial can be obtained, in order to reduce the consumption of air, as a result of the overlapping of these holes by the edges of the dispenser.
