  • Patent number: 8467907
    Abstract: A self-contained valve actuator of the present invention can comprise an actuator component. This actuator can be linear or quarter turn depending on the valve. The actuator can be double acting which means the piston will move once to open and once to close. The self-contained valve system uses hydraulic fluid to operate the valve. The valve system is directly powered with electric power from a battery. Solar panels are also incorporated to capture solar energy and convert this energy into electrical energy. This converted electrical energy is stored in the battery which enables the battery to continuously supply energy while substantially reducing the possibility of exhausting battery power. This resupply of electrical energy and the use of the hydraulic fluid creates a self-contained valve actuation system.

A dirt protection plug is positioned within the chamber and there is a handle for moving it reciprocally or coaxially in the chamber between positions opening and closing communication between said inlet and outlet. The dirt protection plug carries a nose portion which penetrates the outlet seal in the closed position of the gladhand to prevent dirt and other foreign matter from entering the gladhand body chamber. The dirt protection plug carries a closing seal which is in sealing engagement with the chamber walls to close communication between the inlet and outlet in the closed position of the plug.

  • Patent number: 4335747
    Abstract: A connecting device for conduits comprising a female connecting element having an axial bore opening at one end, and a male connecting element adapted to be inserted into the axial bore of the female connecting element. A first ball valve assembly has a housing adapted to be mounted at one end on the female connecting element and formed at the other end with a flat mating surface. In the housing, there is a spherical valve element having a diametrically extending through-hole. The mating surface of the housing is formed with an opening through which a part of the valve element projects. On the male connecting element, there is mounted a second ball valve assembly which is similar in structure to the first ball valve assembly except that the spherical valve element does not project beyond the mating surface but is formed with a part-spherical recess for receiving the projected portion of the valve element in the first ball valve assembly.
