ANTI-SURGE VALVE FOR HYDRAULIC LOCKING DEVICE Abstract of the Disclosure An anti-surge valve for installation in a cylindrical chamber permits a fluid to flow at low velo- city into and out of a port that opens into the cylin- drical chamber and is located on the concave wall of the cylindrical chamber, the valve-preventing a high velocity flow of the fluid from the cylindrical chamber into the port. The valve includes a sealing tube that is positioned within the cylindrical chamber in juxtaposition with the port and coaxial with but spaced radially inward from the portions of the concave wall that surround the port. The sealing tube is maintained in this position by spacers surrounding the sealing tube and extending radially out- wardly to the inner surface of the cylindrical chamber. The anti-surge valve is a unitary structure molded of rub- ber. The sealing tube is sufficiently stiff that at low flow velocities the sealing tube is not drawn toward the concave wall sufficiently to interfere with low velocity flow, but the sealing tube is sufficiently-flexible that at high flow velocities, the sealing tube is drawn against the portion of the concave wall that surrounds the port, thereby sealing the port and preventing high velocity flow of the fluid from the cylindrical chamber into the port.
