A system particularly suited for conveying automobiles in automated car washes having a plurality of expansible fluid conduits sequentially positioned along a path which are adapted to receive fluid under pressure. Fluid pressure may be selectedly supplied to the fluid conduits in response to the location of the automobile wheel on the conduit to establish a conveying force acting on the wheel by expansion of the fluid conduit. For example, this may be accomplished by a pressure sensitive valve or a valve operated by a mechanical position sensor. In the former system, a sensing fluid flow is established through the fluid which is restricted when a wheel of the automobile is positioned on the conduit to create a pressure increase upstream of the restriction which is transmitted to the pressure sensitive valve for opening thereof to supply full operational fluid flow to the conduit. In the latter system, an automobile engaging member may be pivotally mounted and operatively connected to a supply valve to operate the valve upon pivotal movement of the engaging member.
