摘要： A control system for an actuator used to position a control surface on an aircraft such as a horizontal stabilizer, including a source of pressurized fluid, a pressure control for establishing a predetermined pressure level that is substantially one-half source pressure, a blocker valve and at least one direction control valve for controlling the application of fluid pressures to the actuator. During idle periods, the blocker valve supplies substantially equal control pressures to the actuator so that the control system remains pressurized to substantially one-half source pressure. When the actuator is being energized, the direction control valve determines the direction of actuation and the blocker valve controls the fluid flow rate to and from the actuator to maintain a constant actuation rate regardless of load. A servo pressure a regulator monitors return flow across an orifice and adjusts the position of a blocker valve element in order to throttle both the input and return fluid flows to the actuator as a function of the return fluid flow rate so that movement in the actuator is effectively controlled even under overhauling loads.

摘要： A pressure regulating valve which is comprised of a valve body being comprised of a cylinder, a spool slidably disposed in the cylinder with a clearance, the spool and the cylinder defining a pressure chamber and a space portion, and an urging member which urges the spool in a direction opposite to a direction of a force applied to the spool by fluid pressure in the pressure chamber. A supply passage fluidly communicates the cylinder and a fluid pressure supply source, and a drain passage fluidly communicates the cylinder and a sump. A through-passage formed in the spool fluidly communicates the pressure chamber and the space portion. An orifice disposed between the space portion and a sump limits a flow rate of fluid drained from the space portion to the sump. The spool is made of material having a lower thermal expansion coefficient than material of the valve body.

摘要： A pressure insensitive gas process device that includes a gas sensor and restrictions upstream and downstream of the gas sensor. The restrictions result in pressure drops upstream and downstream of the gas sensor which shield the gas sensor from upstream and downstream pressure changes, respectively, rendering the gas sensor and the entire gas process device insensitive to pressure changes. Gas process devices in which pressure insensitivity may be achieved include mass flow controllers as well as other types of devices.

摘要： The disclosure is of a pipeline surge relief system including a valve opened by upstream pressure against a pilot pressure which is normally maintained at the pressure of the pipeline augmented by a slight biasing force. When a detecting system sense an excessive rate of pressure increase indicating a surge in the pipeline, a valve in the pilot loading line downstream of the detector is closed to maintain the pilot pressure at essentially the pressure of the pipeline prior to the surge whereby the surge will cause the valve to be opened to divert the surging flow to a reservoir.

摘要： A quick vent response valve (12) is fluidically series connected between a vacuum regulator valve (14) and an exhaust gas recirculation valve (16) which comprises a fluid pressure control system (10). The quick response valve operates to vent the system more quickly than if the system were vented through the vacuum regulator valve itself by employing the modulated control signal from the vacuum regulator valve as a pilot signal. The quick response valve improves response time of the vacuum system when venting from a high to a low vacuum level by momentarily displacing a valve element (56) disposed within a housing (18) to establish a nonrestricting flow path to atmosphere.
