Abstract
Abstract A fluid valve (10) is disclosed having a butterfly valve member (24) rotatably mounted in a central passage (14) and intermediate first (20) and second (21) fluid ports which fluidly communicate with the central passage (14). Third (22) and fourth (19) ports are in fluid communication with the central passage (14) and spaced at each end thereof. When the valve member (24) is in an open position, the valve defines a pair of isolated fluid flow paths identified by flow through the first (20) and third ports (22) and by flow through the second (21) and fourth ports (19). in the closed position another pair of isolated flow paths ar identified by flow through the first (20) and fourth ports (19) and by flow through the second (21) and third ports (22).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
249 words
Claim 1. A fluid valve for supplying. pressurized fluid to a vehicle heating system heater core, said valve comprising: (a) body means 13, said body means defining (i) an elongated fluid passageway 14, (ii) first 20 and second 21 fluid ports in communication with said fluid passageway, said first and second fluid ports being disposed on opposite sides of said valve body, (iii) a third fluid port 19 in fluid communication with said fluid passageway and spaced longitudinally therealong from said first and second fluid ports, (iv) a fourth fluid port 22 in fluid communication with said fluid passageway and spaced longitudinally therealong from said first and second fluid ports, (b) a valve member 24 rotatably mounted to said valve body and located in said fluid passageway intermediate said first and second fluid ports, said valve member rotatable between first and second positions, such that in said first position said valve member directs fluid flow from said first port through a portion of said passageway to said fourth fluid port and directs flow from said second port through a portion of said passageway to said third fluid port, and in said second position said valve member directs fluid flow from said first port through a portion of said passageway to said third fluid port, in said second position said second and fourth fluid ports are in fluid communication; (c) said first and second ports are located generally at the same longitudinal station along said passageway as said valve member.
Claim 2
Dependent Claim
19 words
Claim 2. A valve as defined in claim 1, wherein said valve member is formed of a metallic material.
Claim 3
Dependent Claim
20 words
Claim 3. A valve as defined in claim 1, wherein said valve member is formed of a stainless steel material.
Claim 4
Dependent Claim
32 words
Claim 4. A valve as defined in claim 1, further including actuator means operably connected to said valve member and energizable for rotating said valve member between said first and second positions.
Claim 5
Dependent Claim
68 words
Claim 5. A valve as defined in claim 1, further including actuator means operably connected to said valve member and energizable for rotating said valve member between said first and second positions, said actuator means including a pneumatically actuated motor having a spring biased de-energized position for maintaining said valve member in said first position and an energized position for actuating said valve member to said second position.
Claim 6
Dependent Claim
303 words
Claim 6. A fluid valve for supplying pressurized fluid to a vehicle heating system heater core, said valve comprising: (a) body means, said body means defining (i) an elongated fluid passageway, (ii) first and second fluid ports in communication with said fluid passageway, said first and second fluid ports being disposed on opposite sides of said valve body, (iii) a third fluid port in fluid communication with said fluid passageway and spaced longitudinally therealong from said first and second fluid ports, (iv) a fourth fluid port in fluid communication with said fluid passageway and spaced longitudinally therealong from said first and second fluid ports, (b) a valve member rotatably mounted to said valve body and located in said fluid passageway intermediate said first and second fluid ports, said valve member rotatable between a first position in fluid sealing engagement with first portions of said passageway and a second position in fluid sealing engagement with second portions of said passageway, such that in said first position said valve member permits fluid flow through said first port to flow through said fourth fluid ports and flow through said second port to flow through said third fluid port, and in said second position said valve member permits fluid flow through said first port to flow through said third fluid ports and through said second and fourth fluid ports; (c) said first and second ports are located generally at a first longitudinal station along said passageway defined by said valve member; (d) said third and fourth ports are located generally at a second longitudinal station relative said passageway, said fourth port being in direct fluid communication with said passageway; and (e) said body means further including auxiliary passageway means for communicating said third port with said elongated passageway at a location remote from said first longitudinal station.
