Abstract: Gas saver valves and methods for gaseous fluid pressure regulation are provided. The gas saver valve has a valve body and a regulator within the valve body for adjusting pressure of a gaseous fluid flowing through the valve body. A control member attached to the regulator allows for the adjustment of the regulator to selectively control the gas pressure of the flowing gaseous fluid. The control member is calibrated with a plurality of marked settings each of which corresponds to a value of gas pressure. The marked settings include a range of gas pressure values that are less than a reference gas pressure for the operation of a heat generating device. The reference gas pressure and the range of gas pressure generate a temperature in an operational range of the heat generating device. An indicator indicates a selected gas pressure when the indicator corresponds to a selected marked setting.

Abstract: Provided is a solenoid valve stable in response performance, whose quickness and damping performance are appropriate. In the solenoid valve, a respiration port for flowing fluid into and out from a space located on one side of a plunger that faces the spool is formed in an end portion of a valve sleeve. Further, a respiration groove, which causes the space on the one side of the plunger and the respiration port to communicate with each other when an end portion of the spool and an end portion of a center post are in contact with each other, is formed on the spool. This configuration makes it possible to discharge, with an appropriate level of flow-channel resistance, fluid placed in the space located on the one side of the plunger.
