Abstract

A liquid pressure limiting valve has a two part housing, the first part forming an inlet 1 and the second part an outlet 8. A pressure plate 11 is slideably and sealingly (by seals 3,4) mounted within the housing between a cap 9 fixed in the outlet 8 and a port forming member 13. Port forming member 13 is mounted in the inlet 1 and a compression spring 12, 5 against which the plate 11 acts, is mounted about the port forming member 13. A port rim 13a is formed on port member 13 against which a seal 4 mounted on plate 11 seats to close the valve. A chamber 14 is formed between cap 9 and port rim 13a, the chamber 14 being connected to the inlet 1 via a passage formed through the seal 4 and a bore 6a of a sleeve 6 mounted in a bore 11g through plate 11. Plate 11 includes two pressure platen surfaces, the first11c being presented to the outlet 8 and the second 11d, which is of a smaller area, to the chamber 14. The seal 4 is preferably formed by a standard “O”-ring and is preferably mounted in a rebate 14 formed in the section of the wall forming the bore 11g of plate 11 adjacent the rim 13a. Preferably a sleeve 6 fits in the bore 11g to compress the seal 4 radially outward so that it will distort to stand proud of the associated end of the plate 11.
