An improved accumulator particularly adapted for use in controlling the pressure of a stream of fluid in its liquid phase utilizing the fluid in its gaseous phase. The accumulator is characterized by a shell defining a pressure chamber having an entry throat for a liquid and adapted to be connected in contiguous relation with a selected conduit having a stream of fluid flowing through the conduit in its liquid phase. A pressure and volume stabilization tube, including an array of pressure-relief perforations is projected into the chamber with the perforations disposed adjacent to the entry throat for accommodating a discharge of the fluid, in either gaseous or liquid phases, while a gas inlet and liquid to gas conversion system is provided for the chamber and connected with a source of the fluid for continuously pressurizing the chamber for controlling the pressure of the stream of liquid.

In combination with a feed system for a rocket engine including a liquid oxygen conduit for conducting a flow of liquid oxygen under pressure between a low-pressure point and a high-pressure point in the system, an improved cryogenic accumulator coupled with said conduit for substantially stabilizing the pressure at which the liquid oxygen is conducted, comprising: A. a shell defining an accumulator chamber and having a liquid oxygen entry port defined therein; B. means connecting said shell to said conduit in a manner such that the chamber is disposed in continuous communication with said conduit via said entry port, whereby pressures established within said chamber continuously are applied to a flow of liquid oxygen within said conduit; C. venting means for substantially stabilizing pressures within said chamber including a pressure and gas volume relief tube connected with the low point in said system and projected into said chamber having fluid exit means disposed adjacent to the entry port for accommodating flow of fluid from said chamber into said tube as the pressure within the chamber exceeds the pressure within the tube, whereby a flow of fluid between said chamber and said low-pressure point is established; and D. means for continuously charging said chamber with oxygen gas including a gaseous oxygen inlet connected with a pressurized source of oxygen gas for continuously delivering flow of oxygen gas to said chamber.
