  • Patent number: 7004062
    Abstract: An elevator pit receptacle and float valve assembly provide for the safe displacement and collection of seeped hydraulic fluid from an elevator cylinder/piston assembly. The receptacle is elevated above the ground yet is below the cylinder seepage ring. A float valve is connected to the ring's drainage hole at one end, and a tube is connected therefrom to the receptacle. Should hydraulic fluid leak into the seepage ring, and the level of such fluid rises above the drainage hole, the fluid drains, by gravity, into the pit receptacle. In the event water intrudes into the elevator pit to a level that reaches the float, as the float rises, the valve shuts closed which prevents an unwanted commingling of water and drained fluid.
