摘要： A steering assistance pump includes a temperature sensor valve which communicates with an inlet duct of the pump by way of an additional, normally closed outlet passage. When a pressure relief valve responds, upon blocking of the servo steering means, the temperature of the hydraulic fluid in the system increases to such a degree that it exceeds the limit value of the temperature sensor valve. The valve thus opens to cause the pilot control pressure in the control chamber of the pressure relief valve to be reduced, whereby the pump pressure itself is also reduced.

摘要： A hydraulic rotary vane pump comprises a flow control valve with a venturi throat disposed upstream thereof whereby the entire delivery flow from the pump passes through the venturi throat. The flow control valve is operable to control the amount of fluid flowing to the delivery outlet of the unit, under the influence of the pressure drop at a restrictor throttle in the form of a bore extending from the throat transversely with respect to the axis thereof. The angle between the axis of the venturi throat and the axis of the bore is between 90.degree. and 150.degree. depending on the degree to which the characteristic of the outlet flow produced is intended to drop off.

摘要： An apparatus for communicating a signal to or from a downhole tool includes a drill pipe configured to be rotated to drill a borehole, a tubular under axial tension and secured in the drill pipe, and a retention device secured to the tubular and configured to maintain the tubular under the axial tension. The retention device includes a portion extending from a body of the device in a direction that is non-inward-radial with respect to a longitudinal axis of the drill pipe. The apparatus further includes a transmission line disposed in the tubular and in an opening of the retention device and in communication with the downhole tool.

摘要： A control system adapted to control an actuator between extended and retracted positions has a fluid control valve connected to the actuator a source of high pressure fluid and a reservoir. The fluid control valve is movable between a first position at which the actuator is connected back to the fluid reservoir adapted and a second position operable to connect the actuator to a high pressure actuation fluid source. An electronic control module is connected in control communication with the fluid control valve and adapted to automatically generate a control signal to position the control valve at the second position in response to an elapsed time being passed at which the fluid control valve is at the first position is greater than a predetermined time.
