    Abstract: A method and apparatus for controlling a speed of a pump operating in a well. A first step involves monitoring a production flow rate of fluids produced from the well. A second step involves controlling the speed of the pump with reference to the production flow rate by increasing the speed of the pump when the production flow rate is rising and decreasing the speed of the pump when the production flow rate is declining.

    Abstract: A variable capacity hydraulic machine has a rotating group located within a casing and a control housing secured to the casing to extend across and seal an opening in the casing. The control housing accommodates a control circuit and a pair of sensors to sense change in parameters associated with the rotating group. One of the sensors is positioned adjacent the barrel on the rotating group to sense rotational speed and the other senses displacement of the swashplate. The control housing accommodates a control valve and accumulator to supply fluid to the control valve.

    Abstract: A fluid pump is provided that produces an outflow of fluid that is not proportional to the speed of the input drive. Thus, the fluid pump can be tuned to provide a substantially constant outflow of fluid irrespective of the speed of the input drive. The fluid pump also provides fluid outflow when the rotational direction of the input drive is reversed.

    Abstract: In many hydrostatic systems, the variable displacement pump is controlled by an operator moving a directional control valve to provide pressurized fluid to the displacement changing mechanism thereof which in turn varies the displacement responsive to the degree of pressurized fluid being directed to the displacement changing mechanism. In order to insure that the displacement of the Variable displacement pump is at the desired displacement, various forms of follow-up mechanisms have been required. These follow-up mechanisms are many times complicated and expensive to add to the hydrostatic system. In the subject arrangement, the speed of the pump input shaft and the speed of the motor output shaft is sensed (R,S) and the signals directed to a microprocessor which in turn processes the signals and directs a control signal (P) to a solenoid operated proportional valve. The solenoid operated proportional valve moves in response to the control signal and directs pressurized fluid to the displacement controller of the variable displacement pump to change the displacement thereof. Once the speed of the output shaft is achieved, the microprocessor modifies the control signal to maintain the variable displacement pump at the needed displacement position to maintain the desired speed of the output shaft to a work system. This arrangement provides an accurate control of the displacement of the variable displacement pump without the need of providing complicated follow-up mechanisms and/or servo mechanisms.

    Abstract: An air tempering apparatus for use in an automotive vehicle having a duct through which air is directed into a passenger compartment. The apparatus comprises an air chilling unit having a variable refrigerating capacity of chilling the air in the duct, and an air reheating unit having a variable reheating capacity of reheating the chilled air in the duct. A control unit decreases the reheating capacity of the air heating unit as the chilled air temperature increases. The control unit decreases the refrigerating capacity of the air chilling means when the reheating capacity of the air reheating means is greater than a predetermined value and when the sensed humidity is less than a predetermined value.

    Abstract: A control system for a variable displacement pump or pumps driven by a vehicular engine for supplying pressurized fluid to implement actuators via implement control valves. The engine has several output conditions each with a different output torque characteristic. The control system includes a servomechanism comprising a servoactuator section coupled to the pump for varying the per cycle displacement thereof, a servovalve section for operating the servoactuator section by fluid pressure from a fixed displacement pump, and a control section for actuating the servovalve section. The servomechanism control section is fluid operated from a torque control valve, which delivers a controlled degree of fluid pressure from the fixed displacement pump to the control section in order to correspondingly vary the torque requirement of the variable displacement pump. The torque control valve is solenoid operated from a controller in association with a sensor capable of sensing each output condition in which the engine operates, in such a way that the torque requirement of the pump is controlled to suit the sensed output condition of the engine. The servomechanism control section is further under the control of a drain sensor effective to control the pump displacement in accordance with the flow rate of the fluid being drained from the implement control valves.
