Abstract

The present invention provides a hydraulic valve for producing a pulsating hydraulic flow without external pilot control. The valve (10) comprises a valve body (12) defining an internal cavity. A main spool (14) is movable in the cavity between first and second positions and divides the cavity into three chambers (28, 30, 32). The body (12) also includes an inlet port (P) connectable to a hydraulic power source, an outlet port (A) connectable to a hydraulic user, a venting port (T), spring means (34) to bias the spool (14) into the first position and a control port (X1)arranged such that pressure applied thereto opposes the action of the spring means (34). The arrangement is such that in the first position pressure applied to the inlet port (P) is communicated to the outlet port (A) and to the control port (X1) and causes the spool (14) to move against the action of the spring (34) into the second position. In the second position, the inlet port (P) is isolated from the outlet and control ports (A, X1), and the outlet port (A) communicates with the venting port (T). In this way, provided that pressure to the inlet port (P) is maintained, the spool (14) will stroke back and forth generating a pulsating flow.
