Abstract: PURPOSE: A control device of air compressor using pneumatic pressure control relay is provided to accurately control pneumatic pressure. CONSTITUTION: A pneumatic pressure control valve(3) and a double-acting air cylinder(5) are connected to a pipe in parallel. The double-acting air cylinder is connected with a relay(7) electrically connected with an air compressor(2) and having a return spring(6). A contacting point(7a) of the relay is cut off to stop the air compressor when pressure in an air tank(1) increases over fixed value. Pressure on which the air compressor is turned on/off is controlled by adjusting tension of the return spring.

Abstract: PURPOSE: A device for preventing electronic wave of an electric fuel pump is provided to prevent wrong operation of electronic components of a vehicle through blocking the electronic wave from the electric fuel pump and a fuel gage by installing an L-C filter between a fuel pump motor and a fuel pump relay, and the fuel gage and a fuel meter. CONSTITUTION: A transformer typed chock coil(L5) is installed between a fuel pump motor(1) and a fuel pump relay(2), and a fuel gage(3) and a fuel meter(4) for attenuating noise from the components. Herein, a low frequency bypass condenser(C1) and a normal chock coil(L1) are installed between the fuel pump motor and a first end portion of the transformer typed chock coil. Normal chock coils(L3,L2,L4) are installed between the fuel pump relay and the other first end of the transformer typed chock coil, between the fuel gage and a second end portion of the chock coil(L5), and between the fuel meter and the other second end portion of the chock coil(L5). Plural low frequency bypass condensers(C2-C4) are connected between first and second ends of the transformer typed chock coil. A zenor diode(Z1) is installed between first and second other ends of the chock coil while installing low frequency bypass condenser between the first other end and a ground terminal.
