摘要： A method of controlling a regulator with a pilot device includes periodically detecting an outlet pressure at an outlet of the regulator with a feedback pressure sensor. The method also includes comparing each detected outlet pressure with a set-point control pressure. Additionally, the method includes opening an exhaust valve when a detected outlet pressure is greater than the set-point control pressure so that a loading gas, which is applied to a top surface of a diaphragm of the regulator, exhausts out through the exhaust valve to reduce loading on the diaphragm. The method further includes sensing a loading pressure in the outlet port with a loading pressure sensor after opening the exhaust valve and comparing the loading pressure to a predetermined minimum threshold pressure. When the loading pressure is equal to or less than the predetermined minimum threshold value, the method includes closing the exhaust valve.

摘要： A joint simulator is provided having a housing with a chamber, a piston, slidable within the chamber, and a shaft rotatable within the housing, the shaft having (i) an end configured to engage a power tool to be tested, and (ii) a threaded end engaged with the piston, whereby rotating the shaft causes the piston to slide within the chamber Hydraulic fluid fills a section of the chamber formed by a side of the piston and the housing, and computer software controlled pressure and relief valves are actuated to regulate the flow of hydraulic fluid in the chamber, to achieve target pressures. The pressure of the hydraulic fluid creates resistance to rotation of the shaft, thereby increasing the torque relative to the angular increase on the shaft and/or relative to time. The joint simulator is provided with means to determine the angular displacement and torque applied to the shaft;

摘要： The present invention relates to a device for regulating the flow rate and/or the pressure of a fluid transferred from a high-pressure reservoir (H) to a reservoir (S). A first valve (1) provided with a control (2) is mounted in a pipe (10, 11, 12) connecting the two reservoirs (H, S). A Laval nozzle (3) located downstream of the first valve (1) is provided with an electrical pressure-drop sensor (4). A second valve (5) provided with a control (6) is connected between the downstream part of the Laval nozzle and an exhaust orifice (R). A micro-programmed system (7), designed to receive the values read by the pressure-drop sensor (4) and to drive the two controls (2, 6) of the two valves (1, 5) makes it possible to regulate the flow rate and/or the pressure of the fluid transferred from the first reservoir (H) to the second reservoir (S).

摘要： A relatively compact and vibration-insensitive electric-to-pressure converter includes an annular flexure from which an annular electromagnetic coil depends into an annular gap defined by the pole pieces of a permanent magnet assembly. A compressed air exhaust nozzle is located below the central region of the flexure which controls the rate of exhaust of air from the nozzle, and therefore the output pressure of the converter, in dependence upon the magnitude of an electrical input current applied to the coil.
