摘要:
A dispensing head for dispensing a cryogenic fluid may comprise a flow passage configured to be placed in flow communication with a reservoir containing a cryogenic fluid, the flow passage defining a flow passage inlet opening configured to receive the cryogenic fluid from the reservoir, and a flow passage outlet opening opposite the flow passage inlet opening. The dispensing head may further comprise a dispensing member configured to dispense the cryogenic fluid, the dispensing member defining a lumen having a lumen inlet opening and a lumen outlet opening; and at least one porous member disposed in the flow passage, the at least one porous member being configured as a primary flow regulation mechanism to limit a flow rate of the cryogenic fluid as it flows from the reservoir to the lumen outlet opening.
