A pump for sensing pressure of vehicles is provided to reduce the output flux and to enlarge the return flow rate by additionally installing a return part mounted to one side of a spool valve. A pump for sensing pressure of vehicles comprises: housing; a rod part controlling the area of an orifice; a spool valve controlling the area of by-pass; a return part(50) formed in the spool valve; and a return hole for transferring the fluid inflowing through the return part. The return part includes: a case(52) in which a path(52a) is formed while being curve-cut; a spring(54) fixed to the inner one-side of the case; a ball(56) positioned in the spring in order to open and close the path; and a support stand(58) supporting the ball. |
