专利汇可以提供Fluid actuated track system with constant flow valve专利检索，专利查询，专利分析的服务。并且A toy system having transparent conduit forming a track for projectiles such as toy trains propelled by air or water. A constant flow-type valve admits the fluid from a source of air or water under pressure controlling the rate of fluid admission to the conduit track to control the speed of the projectile along the track. The track is arranged in various configurations including closed loops and parallel straight drag strips. Indicating devices are included for counting the laps traversed by projectiles on the closed tracks and for indicating a winner in the drag strip arrangement.，下面是Fluid actuated track system with constant flow valve专利的具体信息内容。
1. A fluid operated toy system for propelling a member along a track comprising: a track system of selected configuration comprising a transparent conduit permitting observation of movement of said member along said track, said track system having means providing a fluid inlet thereto and a fluid outlet therefrom; control valve means connected with said track system for controlling fluid flow into said system; said valve means being a constant flow-type valve having means for constant input flow and means for diverting fluid in excess of the desired output from said valve means out of said track system whereby said valve means controls the volume of flow of fluid into said track system for varying the speed of said member along said track system while permitting constant maximum fluid input to said valve means; and means for connecting a source of fluid pressure to said valve means.
2. A fluid operated toy system in accordance with claim 1 including a flow conducting fitting between said valve means and said track system for directing the discharge of fluid from said valve means into said track system and said fitting including means for accelerating the fluid flow into said system, and fluid spillage means providing a fluid outlet from said system downstream from said control valve means and at the inlet to said track system from said valve means.
3. A fluid operated toy system in accordance with claim 1 wherein said track means comprises parallel drag strip track sections, each of said sections being provided with one of said control valve means for independent control of fluid flow into each of said drag strip sections whereby movable members in each of said sections may be raced against each other along said drag strip sections.
4. A fluid operated toy system in accordance with claim 3 including a Y fitting between said valve means and each of said drag strip sections, the trunk portion of said Y fitting being connected with the inlet end of said drag strip section, said Y fitting having a first arm portion connected with said control valve means for directing fluid flow into said drag strip section, and said Y fitting havIng a second arm portion having an open end for insertion of a movable member into said fitting for introduction through said fitting into said drag strip section.
5. A fluid operated toy system in accordance with claim 5 including a flag unit connected with said drag strip sections at the outlet ends thereof for indicating a winner between the movable members moving along said sections, said unit being adapted to be actuated by said members moving through said drag strip sections to operate an indicator device for showing which of said members arrived at said flag unit first.
6. A fluid operated toy system in accordance with claim 4 including fluid accelerating means in said first arm of said Y fitting.
7. A fluid operated toy system in accordance with claim 1 wherein said track system comprises a closed loop; a fluid conducting Y fitting included in said closed loop connecting said loop with said control valve means, said Y fitting having a trunk portion provided with air spillage means connected with an inlet portion of said closed loop and having a first inlet arm connected with said control valve directing fluid flow into said Y fitting and second arm connected with an end portion of said closed loop whereby said second arm and said trunk portion close said loop to provide a continuous track for movement of said member.
8. A fluid operated toy system in accordance with claim 7 including fluid accelerating means in said first arm of said Y fitting.
9. A fluid operated toy system in accordance with claim 7 wherein said closed loop includes an entrance-exit unit having a valve plate to admit said member to said closed loop and to permit exit to said member from said closed loop.
10. A fluid operated toy system in accordance with claim 9 wherein said track system includes two said closed loop tracks each including identical fluid flow control valves and Y fittings connecting said loops with said source of fluid pressure and permitting independent control of the movement of a member along each of said closed loops.
11. A fluid operated toy system in accordance with claim 9 including a lap counter connected with said closed loops permitting movement of said movable members through said counter for indicating the number of times the movable member in each of said loops has traversed said loop.
12. A fluid operated toy system in accordance with claim 1 wherein said valve means includes a body having a central flow passage communicating with said track system and through which said member is movable, said body having an opening into said central flow passage along a side of the said valve means, and a valve plate pivotally supported for movement between a full open position at which said valve plate is disposed in said opening permitting full flow through said central flow passage of said valve means and preventing fluid escape from said flow passage and a second fully closed position at which said valve plate is disposed across said central flow passage precluding fluid flow through said flow passage and diverting fluid flow outwardly from said track system through said opening, fluid flow through said central flow passage being apportioned at intermediate positions of said valve plate whereby one portion of said fluid flow continues through said central flow passage and another portion of said fluid flow is diverted from said central flow passage through said opening for varying the rate of movement of said member through said track system.
