220.127.116.11. Oil pressure regulator (reducing valve)
The oil pressure regulator (the reducing valve) performs function of prevention of excess supply of oil. At low frequencies of rotation the regulator valve under the influence of a spring blocks perepuskny (bypass) the channel. Whereas at high frequencies of rotation, pressure of oil increases, the pressure force of oil overcomes effort of a spring, and the valve of the regulator opens. Excess oil via the valve comes back to the pallet.
