The invention relates to an oil supply valve body for testing an ECU (Electronic Control Unit) of an automobile brake. The lower end of a first adjusting valve is communicated between the two ends of a longitudinal pipe arranged between a first oil inlet and a first oil outlet; the end part of a longitudinal pipe connected with a second oil inlet is communicated with the lower end of a second adjusting valve; the bottom surface of the second adjusting valve is communicated with a second oil outlet through the other end of the longitudinal pipe; the bottom surface of the first adjusting valve is communicated with a transverse pipe through a vertical pipe; one end of the transverse pipe is communicated with an assembly port formed on one end face of a base; the other end of the transverse pipe is communicated with a longitudinal pipe between the second adjusting valve and the second oil outlet; and a longitudinal pipe between the first oil inlet and the first adjusting valve and a longitudinal pipe between the other end of the transverse pipe and the second oil outlet are communicated with a pressure contactor installation hole formed on the bottom surface of the base respectively. In the invention, three oil pipes with three oil paths for supplying oil or four oil pipes with four oil paths for supplying oil can be directly connected to an oil inlet on the base, so that an oil supply valve body is not required to be replaced frequently, great convenience is brought, and the service life of the oil supply valve body is prolonged.
