Abstract

A dash-pot valve comprises a cylinder submerged in the fluid of a housing and have a piston attached to a plunger projecting into the path of closing movement of a pivotal valve member. A vortex chamber in said cylinder is provided with targentially directed inlets to generate vortex flow upon retraction of said plunger and effect increasing resistance against said piston to progressively retard the closing rate of said valve member toward its seat.

Valve and dash-pot assembly

Patent Chang, S.-C.

A value and dash-pot assembly is described comprising: a housing having a valve seat, a valve member pivotally mounted in the housing between a valve open position and a valve closed position engagable against the seat, a dash-pot valve submerged in the fluid within the housing and including a cylinder formed with an end wall having an outlet, and having a reciprocal piston, a plunger attached to the piston and projecting outwardly of the cylinder in the path of closing movement of the valve member, a chamber in the cylinder, means for normally biasing the piston and attached plunger outwardlymore »« less
Valve and dash-pot assembly

Patent Chang, Shih-Chih (Richland, WA)

A dash-pot valve comprising a cylinder submerged in the fluid of a housing and having a piston attached to a plunger projecting into the path of closing movement of a pivotal valve member. A vortex chamber in said cylinder is provided with tangentially directed inlets to generate vortex flow upon retraction of said plunger and effect increasing resistance against said piston to progressively retard the closing rate of said valve member toward its seat.

Tank vapor vent valve assembly with improved overfill protection

Patent Gifford, W.E.; Sherwood, C.H.; Covert, C.H.; ...

This patent describes an improvement in a vehicle fuel tank vapor recovery system of the type that has a vapor storage canister and a tank vapor vent valve assembly that routes the flow of fuel vapor displaced from the fuel tank during fuel fill to the canister, but which blocks liquid fuel from reaching the canister. It comprises: a lightweight and buoyant float with an elongated axis having a seal at its upper end, a float chamber through which the flow of displaced tank vapor passes, the chamber having an interior wall within which the float is slidably received somore »« less
Closure device for fuel assembly pot. [LMFBR]

Patent Pomie, P.; Renaux, C.

Handling device is described for a fast neutron reactor cooled by a liquid metal such as sodium and of the type comprising a container with a vertical axis containing the core and a given volume of sodium contained in said container, defining above the core a free level surmounted by an inert gas cushion, a thick horizontal slab placed above the gas cushion and constituting the upper closure of a protective caisson surrounding the container, an inclined ramp which passes into the container up to a loading and unloading station located in the vicinity of the core and extending atmore »« less
Internal combustion engine with rotary valve assembly having variable intake valve timing

Patent Hansen, C.N.; Cross, P.C.

An internal combustion engine has rotary valves associated with movable shutters operable to vary the closing of intake air/fuel port sections to obtain peak volumetric efficiency over the entire range of speed of the engine. The shutters are moved automatically by a control mechanism that is responsive to the RPM of the engine. A foot-operated lever associated with the control mechanism is also used to move the shutters between their open and closed positions. 21 figs.
