Abstract: A flow control valve having a body with an inlet port, an outlet port and an access opening. The body has a cavity connecting with the access opening and communicating between the inlet and outlet ports. A single pair of discs with orifices is located within the cavity. One disc is secured to the bonnet which extends into the cavity and the other is attached to a rotatable turning fork which rotates to change the alignment of the disc orifices thereby controlling flow to the outlet port. The bonnet and the turning fork have openings which allow fluid to flow from the inlet port to the discs. The bonnet attaches over the access opening and secures the turning fork, the discs, a wear insert and a lower seat within the cavity. An o-ring holds the valve assembly together as it is installed and removed from the valve body.

Abstract: A fuel introduction member is connected to an open end of a siphon tube which constitutes a part of a fuel tank. The fuel introduction member is provided with an opening through which a fuel is introduced from the tank into the siphon tube and from the siphon into the tank, a lid portion which is swung by the hydraulic pressure from the siphon tube so as to open the opening, and a float member which floats on the fuel in accordance with the rise of a fuel liquid surface in the tank to displace the lid portion in order to open the opening.

Abstract: In a hydrant assembly, the combination comprising an outer tubular member having a first flow port.; an inner tubular member having a closure thereon to close the port in relatively axially advanced position of the closure, and to open the port in relatively axially retracted position of the closure that allows fluid flow through the port to an outlet, control means to control relative movement of the inner and outer members. A second port may be located sidewardly of the outer tubular member to pass fluid in relatively retracted position of the closure to relieve fluid pressure in space formed between the inner and outer members, the inner member being elongated and extending lengthwise in the outer tubular member. The outer tubular member may consist of plastic material. Travel of the closure acts to allow expansion of fluid as it freezes, to relieve pressure build-up within the assembly.

Abstract: A portable remote controlled fire-fighting valve has a central chamber in a main valve body, an inlet that connects to a hydrant, an outlet that connects to a fire hose, a valve mechanism that has a seating surface that seats against part of the device to open and close a flow channel through the central chamber, and a remote controller that enables an operator to selectively open and close the flow channel. The valve mechanism uses a piston that is mounted for axial movement within the central chamber. The piston has an annular wall that slides against an outer edge of a lateral chamber surface that is fixed in position within the main valve body. A spring biases the piston to the closed position. In the open position, water from the inlet flows around the piston, over its peripheral surface, to the outlet. A pressure chamber is formed between a lateral surface that is fixed in position within the valve body and a movable interior surface on the piston.
