Abstract
A system for pressurizing liquid is described herein. The system may include a liquid reservoir and a pump coupled to the liquid reservoir, the pump to draw liquid from the liquid reservoir. A compliant volume coupled to the pump receives liquid from pump. The compliant volume is composed of an elastic material to increase pressure of the liquid. A valve coupled to the compliant volume receives pressurized liquid from the compliant volume.
Claims15
A system for pressurizing liquid, comprising:
- a liquid reservoir;
- a pump coupled to the liquid reservoir, the pump to draw liquid from the liquid reservoir;
- a compliant volume coupled to the pump to receive liquid from pump, the compliant volume composed of an elastic material to increase pressure of the liquid as volume of the compliant volume is increased;
- a valve coupled to the compliant volume to receive pressurized liquid from the compliant volume, wherein an input pressure to the valve is varied by the compliant volume;
- and
- a vaporizer coupled to the valve to receive the liquid from the valve, wherein a flow rate of the liquid is based, in part, on an elastance of the compliant volume.

A method for pressurizing liquid, comprising:
- drawing liquid by a pump from a liquid reservoir;
- receiving liquid from pump at a compliant volume coupled to the pump, wherein the compliant volume is composed of an elastic material to increase pressure of the liquid as volume of the compliant volume is increased;
- receiving pressurized liquid from the compliant volume at a valve coupled to the compliant volume, wherein an input pressure to the valve is varied by the compliant volume;
- and
- receiving the liquid from the valve at a vaporizer coupled to the valve, wherein a flow rate of the liquid is based, in part, on an elastance of the compliant volume.
