摘要： Vehicle washing equipment comprises a cleaning brush on a swing arm. The arm is biased towards a rest position and is deflected from this position by a vehicle so that the brush follows the contours of the vehicle. To allow fast drive through of several vehicles it is desirable to arrange for the brush not to return to its rest position between vehicles. According to the invention, washing equipment comprises selectively operable hydraulic non- return means comprising a piston and cylinder unit 20 coupled to the swing arm for movement of the piston with movement of the arm. Fluid passes from one side of the piston to the other through conduit means comprising a non-return valve 28 and a solenoid-operated valve 30 arranged hydraulically in parallel with the valve 28 to prevent, when actuated, return of the arm whilst permitting further outwards movement.

摘要： Vehicle washing equipment in which rotary brushes 1 are carried on arms 4 pivoted about vertical axes so that each brush 1 can swing in an arc between an advanced position in which it presses against the side of a vehicle and a retracted position in which it is clear of the vehicle. Each arm 4 is normally held in the parked position against a fixed stop 7 by a spring 8. The arms 4 have hydraulic actuators in the form of bellows-like rubber bags 9 for moving the brushes 1 into the advanced position, and these actuators use as their source of power the same water supply as is used to feed nozzles on spray bars 14 for spraying water onto the vehicle. The water is fed to the actuator bag 9 via a control system 13.

摘要： 871,817. Brushes. SMITH BROS. & WEBB Ltd. April 21, 1960 [Feb. 12, 1959], No. 4898/59. Addition to 769,423. Class 19. The rotatable brush for washing vehicles as described in the parent Specification is modified in that the lower of the axially spaced rotor discs 2-6 between which the brush units are secured are of smaller diameter than the rest of the discs so that the axially configuration of the brush is sinusoidal, being uncurved at the lower end of the brush.
