Abstract

A pressure reducing valve for coupling to a pressurized water supply line includes a valve body with an inlet for coupling to the pressurized water supply line, an outlet, a passage extending between the inlet and the outlet, and a valve seat in the passage. A valve stem extends into the passage, which has a sealing member. An automatic pressure reducing system is provided for urging the sealing member toward the valve seat for throttling the valve to thereby reduce the pressure at the outlet. The automatic pressure reducing system includes parallel springs that occupy less space than conventional springs for a given spring load.

Claims

AMENDED CLAIMS received by the International Bureau on 09 Aug 2006 (09.08.06)The embodiments of the invention in which an exclusive properly righl or privilege is claimed are defined as follows:
1. A pressure reducing valve for coupling to a pressurized water supply line, said valve comprising: a valve body with an inlet for coupling to the pressurized water supply line, an outlet, and a passage extending between said inlet and said outlet, said valve body having a valve seat in said passage al or adjacent said inlet; a valve stem extending into said passage, said valve stem having a sealing member; an automatic pressure reducing system for urging said scaling member toward said valve seat for throttling said valve to thereby reduce the pressure at said outlet; and a manual system coupled to said sealing member and for urging said sealing member toward said valve seat, said manual system being decoupled from said pressure on said piston wherein said manual system is decoupled to from said automatic pressure reducing system such that said manual system ear urge said sealing member toward said valve seat without, having to overcome said pressure on said piston.
2. The pressure reducing valve according to Claim 1, wherein said automatic pressure reducing system comprises a piston mounted to said valve stem, said valve further comprising a chamber, the water pressure at said inlet being directed to said chamber and applying pressure on said piston to apply a load on said valve stem to utge said sealing member toward said valve seat to adjust the pressure at said outlet.
3. cancelled
4. The pressure reducing valve according to Claim 2, further comprising a spring, said spring coupled to said valve seem and generating a spring force opposed to said pressure on said piston to adjust the load on said valve stem and to thereby adjust the pressure at said outlet.
5. The pressure reducing valve according to Claim 4, wherein said manual system is decoupled from said pressure on said piston and said spring force of said spring to facilitate dosing of the valve wherein said manual system can urge said sealing member toward said valve seat without having to overcome said spring force or said pressure on said piston.
6 The pressure reducing valve according to Claim 4, wherein said manual system includes a hand operable member, said hand operable member coupled to said valve stem and being movable to urge said scaling member toward said valve seat, and wherein movement of said hand operable member is decoupled from said pressure on said piston and said spring force of said spring.
7. The pressure reducing valve according to Claim 6, wherein said valve stem includes a first valve stem portion coupled to said piston and said spring, said valve stem including a second valve stem portion coupled to said hand operable member.
8. The pressure reducing valve according to Claim 7, wherein said second valve stem portion is guided by said first valve stem portion and movable relative to said first valve stem portion.
9. The pressure reducing valve according to Claim 8, wherein said first valve slem portion comprises an outer valve stem portion, said second valve stem portion comprising an inner valve stem portion guided in said outer valve slem portion.
10. A pressure reducing valve for coupling to a pressurized water supply line, said valve comprising: a valve body with an inlet for coupling to the pressurized water supply line, an outlet, and a passage extending between said inlet and said outlet, said valve body having a valve seat in said passage at or adjacent said inlet; a housing mounted to said valve body, said housing including a chamber; a valve stein extending through said chamber and into said passage, said valve stem having a sealing member for sealing said valve seat; said valve stem including a piston, said piston located iu said chamber, and said valve slem having a passageway in communication with said passage and said chamber, wherein water at the inlet flows through said passageway into said chamber and exerts pressure on said piston wherein said piston applies an urging force to said valve stem to urge said sealing member of said valve slem toward said valve seat to thereby restrict the flow of water through said inlet;
