Abstract
A wash spray apparatus that is particularly suitable for use in automatic car washes comprises an array of nozzles on a nozzle head. Water is supplied to the nozzle head through one or more flexible hoses, and the nozzle head is driven so that the spray from the nozzles moves through a conical path. The drive is effected by an hydraulic motor connected to the nozzle head through a nutating mechanism which produces the desired movement of the spray without rotation of the nozzle head.
