Definitions

  • the present invention relates to three-way valves.
  • Conventional val ve arrangements of the type that are used for oil temperature control in, e.g., diesel engines are driven by a solenoid and are often limited by the manner of operation of the solenoid and the valve packaging.
  • Conventional designs only allow for valve windows to be as tall as a distance that a spool of the valve can travel. This has limited the design to very small windows through which 100% of the oil must travel.
  • Another limitation of conventional oil temperature control valves is a complex force balance due to the effect of oil flow into the valve which makes control very difficult.

  • the valve 21 can facilitate maximization of the flow area through the valve as up to 180° of a circumference of the valve can be open. This can also help in reducing pressure drop across the valve. Reducing the pressure drop helps to make the oil system more efficient and ultimately contributes to fuel economy.
  • the valve 21 will also not create any or will minimize areas where pressure or flow can act on the valve to create an unbalanced system as there need not be surfaces against which the pressurized fluid can act so that the valve will not have to act against any flow and will only have to overcome frictional forces in the valve itself in order to turn.
  • the valve 21 is particularly useful as an oil temperature control valve and can facilitate providing greater control of oil temperature and, in turn, can assist in enhancing system efficiency and fuel economy.
  • the valve 21 may. of course, be used in other applications.

Un boisseau tubulaire est disposé dans la cage de vanne et comporte une première ouverture de boisseau dans une surface latérale de boisseau à une première position axiale et circonférentielle de boisseau et une seconde ouverture de boisseau dans la surface latérale de boisseau à une seconde position axiale et circonférentielle de boisseau. Le boisseau peut tourner autour de son axe longitudinal par rapport à la cage entre une première position dans laquelle la première ouverture de cage et la première ouverture de boisseau sont alignées, et une seconde position dans laquelle la seconde ouverture de cage et la seconde ouverture de boisseau sont alignées et définissent ensemble une seconde ouverture de vanne.
