  2. Radio-controlled glider - Wikipedia

    en.wikipedia.org/wiki/Radio-controlled_glider

    As full-size winch launching but using a small electric motor (usually based on a car starter motor) and a reverse pulley staked to the ground upwind. The launch speed is controlled by the pilot using a foot pedal. [3] A parachute is used (pulled shut by the launch tension) to assist in preventing the winch spool overrunning when the model is ...

  3. Variable valve lift - Wikipedia

    en.wikipedia.org/wiki/Variable_valve_lift

    Variable valve lift (VVL) is an automotive piston engine technology which varies the height a valve opens in order to improve performance, fuel economy or emissions. There are two main types of VVL: discrete, which employs fixed valve lift amounts, and continuous, which is able to vary the amount of lift.

  4. Remotely operated underwater vehicle - Wikipedia

    en.wikipedia.org/wiki/Remotely_operated...

    ROV at work in an underwater oil and gas field. The ROV is using a torque wrench to adjust a valve on a subsea structure.. A remotely operated underwater vehicle (ROUV) [citation needed] or remotely operated vehicle (ROV) is a free-swimming submersible craft used to perform underwater observation, inspection and physical tasks such as valve operations, hydraulic functions and other general ...

  5. Active heave compensation - Wikipedia

    en.wikipedia.org/wiki/Active_heave_compensation

    [4] [5] Hydraulic "active boost" winches control the oil flow from the pump(s) to the winch so that the target position is reached. Hydraulic winch systems can use accumulators and passive heave compensation to form a semi-active system with both an active and a passive component. In such systems the active part will take over when the passive ...

  6. Desmodromic valve - Wikipedia

    en.wikipedia.org/wiki/Desmodromic_valve

    A desmodromic valve is a reciprocating engine poppet valve that is positively closed by a cam and leverage system, rather than by a more conventional spring. The valves in a typical four-stroke engine allow the air/fuel mixture into the cylinder at the beginning of the cycle and exhaust spent gases at the end of the cycle. In a conventional ...

  7. Shuttle valve - Wikipedia

    en.wikipedia.org/wiki/Shuttle_valve

    Winch brake circuit: a shuttle valve provides brake control in pneumatic winch applications. When the compressor is operated the shuttle valves direct air to open the brake shoes. When the control valve is centered, the brake cylinder is vented through the shuttle valve, and the brake shoes are allowed to close. [clarification needed]

  8. Pilot-operated relief valve - Wikipedia

    en.wikipedia.org/wiki/Pilot-operated_relief_valve

    A separate actuator on the piping releases pressure in the line if it crosses a threshold. This releases the pressure on the back of the seal, causing the valve to open. The essential parts of a PORV are a pilot valve (or control pilot), a main valve, a pilot tube, the dome, a disc or piston, and a seat. The volume above the piston is called ...

  9. Mass flow controller - Wikipedia

    en.wikipedia.org/wiki/Mass_flow_controller

    The MFC is fitted with a closed loop control system which is given an input signal by the operator (or an external circuit/computer) that it compares to the value from the mass flow sensor and adjusts the proportional valve accordingly to achieve the required flow. The flow rate is specified as a percentage of its calibrated full scale flow and ...
