Abstract: The invention concerns a regulating valve for the discharge of liquid from a container comprising a movable main valve body for opening and closing an outlet opening for the liquid to be discharged, and a movable pilot valve body for controlling the main valve body, characterized in that the main valve body and the pilot valve body are mechanically coupled together at least in one position relative to each other.

Abstract: A float bell for use in a condenser comprising a center sleeve extending along a centerline comprising a first and second perimeter, an outer sleeve comprising a first and second perimeter encompassing the center sleeve, a top in contact with the second perimeter of the outer sleeve and the second perimeter of the center sleeve, and a plurality of stiffeners extending between the center sleeve and the outer sleeve.

Abstract: A combination pump and trap is disclosed which includes a snap-over mechanism useful for small floats with little buoyancy. The snap-over mechanism has a geometry in which the distance between the float or compression arm pivot point and the pivot for the portion of the spring connected to a first arm or toggle link is greater than the distance from the float or compression arm pivot point and the pivot for the portion of the spring connected to the float or compression arm. This geometry allows the magnification of buoyancy by the main arm which is transmitted to the first toggle link to be large and the magnification of buoyancy by the first toggle link which is transmitted to the change-over valve to be large. A trap which is connected to the float arm is also used, which allows a liquid seal to be maintained at the liquid discharge port.

Abstract: A gas separation valve assembly for a diesel motor system having a tank with a float therein controlling a valve mechanism through which fuel is dispensed from the tank. A dual sleeve assembly is arranged within the tank having an inner sleeve with a lower end in fluid-tight connection with the tank and an outer sleeve arranged to define an annular space between itself and the outer wall of the tank and an intermediate space between itself and the inner sleeve. Fuel is introduced into the tank through an aperture so as to flow into the annular space between the tank wall and the outer sleeve and then to pass through the intermediate space so as to overflow the inner wall and to flow into an interior space of the tank within which the float is located.

Abstract: A valve assembly controlled by a float permits pressure-free feed of a fluid into a pipeline system, the valve being assigned in operative relationship with a channel which is arranged in the base of the tank containing the float, the channel extending laterally to the normal axis of the tank. The valve is designed as a dual valve with two valve members arranged on a valve rod guided in the direction of the axis of the tank and the channel is defined through a pair of apertures lying opposite each other in the direction of the axis of the tank with valve seats being located about the apertures, the valve members arranged on the valve rod operating to engage and disengage the valve seats to open and close the apertures.

Abstract: A T-shaped pipe whose base extends through a sidewall of a steam trap housing terminates internally of the housing in open ended upper and lower vertical arms. The lower arm is closed off by an axially movable valve disc mounted to a valve actuator rod extending axially through the arms and coupled at its upper end to a pressure balancing plate sealably connected at its periphery by a non-ferrous metal bellows to the upper end of the T-pipe arm. A float ball fixed to a float arm is pivotably coupled at the opposite end of the arm to the valve actuator rod and to the T-pipe with the pressure on balancing plate balancing the pressures acting on the movable valve disc.
