Retractable overhead nozzle system for car wash blower

An assembly for blowing liquids from a vehicle comprising;

• a support plenum (12) for distributing air,
• a nozzle plenum (18),
• a nozzle (20) depending from said nozzle plenum (18) for directing air toward a vehicle,
• an upper tube (26) having an interior and movably supported by said support plenum (12) for movement into and out of said support plenum (12) and a lower tube (28) in telescoping relationship within said interior of said upper tube (26) for delivering air from said support plenum (12) to said nozzle plenum (18) while allowing said nozzle plenum (18) to move vertically in an adjustment direction toward and away from said support plenum (12) between various operating positions,
• an axle (30) supporting said nozzle plenum (18) for rotary movement relative to said lower tube (28) about said axle (30),
• said axle (30) extending through said lower tube (28) for raising said nozzle plenum (18) and telescoping said lower tube (28) into said upper tube (26) and said upper tube (26) into said support plenum (12) during vertical movement between said various operating positions whereby said nozzle plenum (18) may be moved up and down to accommodate the changing longitudinal configuration of a vehicle and said nozzle plenum (18) may be rotated about said axle (30) to efficiently direct air against the contour of the vehicle.
