  • Patent number: 6546839
    Abstract: The present invention relates to a flow regulation device for mitigating over travel of a piston in a fluid operated tool. The flow regulation device includes a flow channel through which flows an operating fluid to be supplied to operate the piston within the tool and a movable flow restrictor within the flow channel. The flow restrictor has an internal fluid passageway for regulating the flow rate of the operating fluid being supplied to the tool to operate the piston. The flow restrictor also has a frustoconical portion which mates or seats against a portion of the flow channel as fluid is being supplied to operate the piston. A spring is provided to insure that the frustoconical portion seats against the mating portion of the flow channel. When the piston is retracted and operating fluid is being returned to a supply, the force applied by the spring is overcome and the flow restrictor is moved so that the frustoconical portion is unseated from the mating portion.
