Improved brake pressure control valve assemblies with a bypass function are proposed which have an axially slidable piston responsive to fluid pressures of two brake fluid circuits, and a pressure reducing valve mounted in the piston for reducing the pressure of one of the two brake fluid circuits. If one of the circuits fails, the piston is adapted to move toward the failed circuit to disable the pressure reducing valve from reducing the pressure of the other of the two circuits.

The degree of opening of the expansion valve in refrigeration system is controlled by means of PID control such that a refrigerant superheat at the outlet of the evaporator approaches a target valve. Since an elapsed time after the start of the refrigeration system varies in response to a change of a heat load of air to be cooled by the evaporator, if the control constant of the PID control is designed so that the expansion valve can be controlled adequately for high evaporator heat load, or for low evaporator heat load, adequate control cannot be achieved in the opposite case not taken into consideration in design. According to the present invention, the control constant of the PID control is varied when an elapsed time after the start of the refrigeration system reaches a reference time which is determined on the basis of a heat load of air to be cooled by the evaporator.
