Abstract: When a drive signal is not applied to a piezoelectric element 42, a diaphragm 38 is contacted with a valve seat 52 to disconnect diaphragm chambers 24a, 24b from a passage 54. In this case, even if the pressure of a fluid introduced into the diaphragm chambers 24a, 24b is varied, the diaphragm 38 is positively supported by a valve seat 52 with no deformation, resulting in the passage 54 being positively closed up. Therefore, the possibility of the fluid leaking is eliminated. On the other hand, when a drive signal is applied to the piezoelectric element 42, the diaphragm 38 is bent, and thus the diaphragm chambers 24a, 24b are connected with the passage 54, resulting in the fluid being allowed to flow into the passage 54. If the piezoelectric element 42 comes to bend excessively, the piezoelectric element 42 is brought into contact with a cushioning member 56 to prevent the piezoelectric element 42 from being excessively deformed.

Abstract: A multiple-bore throttle valve wherein the valve shaft is restrained from end play at a point between two of the flow bores. A passageway in the valve body between the flow bores intersects the valve shaft bore non-diametrically. The valve shaft has a circumferential groove at the point of intersection. A pin pressed into both the passageway and the groove axially restrains the shaft at that location. Since thermal expansion or contraction of the shaft in its axial direction can proceed only from the point of restraint, a dual-bore valve in accordance with the invention exhibits length changes in each bore equivalent to that of a single bore valve, which is less than half the shaft length change exhibited in at least one bore of a prior art dual-bore throttle valve. Similarly, a triple-bore valve exhibits expansion comparable to individual prior art single-bore and dual-bore valves, and a quadruple-bore valve exhibits expansion comparable to a prior art dual-bore valve.

Prior to introducing liquefied gas into the gas cylinder, a cleaning process is carried out using a two-step baking process to clean the surface of the nickel-phosphorus layer. The nickel-phosphorous layer substantially reduces the contamination of liquefied corrosive gasses stored in the gas cylinder by metal from the steel wall surface underlying the nickel-phosphorous layer.
