APPARATUS FOR COMPRESSED AIR PRESSURE ADJUSTMENT AND DRYING Russian patent published in 1997 - IPC

FIELD: apparatuses for compressed air adjustment and drying in pneumatic motor systems of transportation means. SUBSTANCE: apparatus has body, safety valve, butt lid, card, outer hood, filter, piston, sleeve, force spring, discharge valve, ring with beads, stopping member. Piston and sleeve are mounted between outlet cavity and atmospheric cavity. Sleeve has throttle canal capable to connect over piston cavity with outlet cavity and with cavity communicated with atmosphere through clearance between piston and sleeve. The apparatus for drying and adjustment of compressed air allows to increase reliability of operation, to keep given parameters of compressed air pressure adjustment, to decrease noise level, to increase degree of preliminary moisture separation, to decrease costs of maintenance. EFFECT: increased operational reliability, pressure parameters stability, moisture separation, decreased noise level, maintenance costs. 3 cl, 3 dwg
