Abstract
In a rail system one or more hydraulic assemblies comprising a movable cylinder (6) with a wheel-engaged rounded head (7) and a fixed piston (4) within the cylinder (6) are located adjacent a running rail (1). When engaged by passing rail wheels (2) the assembly provides pressurized fluid which is fed into a pressure line which leads to means for switching a set of points. Energy is thus extracted from moving rail vehicles and it is unnecessary to provide long-distance power supplies to a set of points.
Claims8
A rail system for vehicle transport having
- (a) a rail track of spaced apart parallel rails,
- (b) a set of points,
- (c) hydraulically operated means for switching said set of points,
- (d) a hydraulic piston-and-cylinder assembly located next to one of said rails of said rail track and having an element projecting into the path of the rail wheels of a rail vehicle passing on said track to be engaged thereby so that the said assembly is actuated by passage of a rail vehicle to provide pressurised fluid, and
- (e) a pressure line connecting said piston-and-cylinder assembly to said points switching means whereby said pressurised fluid from the assembly is usable to operate the points switching means.
In a rail system for vehicle transport having a hydraulic piston-and-cylinder assembly located next to a rail and arranged to be actuated by the rail wheels of a passing vehicle, the improvement that the piston-and-cylinder assembly is adapted and arranged to provide pressurised hydraulic fluid on being actuated by a passing wheel and the assembly is connected to a pressure line for supply of said pressurised fluid from the assembly to means for switching a set of rail points.
