1. A valve comprising: a housing forming one inlet and at least one outlet including a first outlet and a second outlet, and adapted such that a fluid flows into an interior thereof through the one inlet; andan operating unit mounted in the housing, and performing expansion or contraction in accordance with a temperature of a flowing working fluid to selectively connect the at least one outlet with the one inlet for exhausting the flowing working fluid outside of the housing,wherein the operating unit comprises: a sliding member adapted such that both ends thereof are opened, a first open hole and a second open hole are respectively formed at both sides corresponding to each other along a length direction thereof to correspond with the one inlet and the at least one outlet, and slidably inserted into the interior of the housing;a flange member forming a penetration hole at a center thereof, and fixedly mounted on a first end inside of the sliding member;a rod movably inserted into the penetration hole of the flange member;a deformable member adapted such that a first end thereof is fixed at the penetration hole of the flange member in a state of being engaged to a first end of the rod in the sliding member, and expanded or contracted in accordance with a temperature of the flowing working fluid to move the sliding member in the housing backward or forward on the rod;an elastic member interposed between the housing and the deformable member to provide an elastic force to the deformable member according to being compressed or expanded by the deformable member moved backward or forward on the rod; andan end cap mounted at an opened first end of the housing, and adapted to close the interior of the housing and to support a second end of the rod,wherein the one inlet is provided to the housing, and the valve is a 4-way valve which has the first outlet formed apart from the one inlet, the second outlet disposed between the one inlet and the first outlet and formed at the opposite side to that of the one inlet to exhaust the flowing working fluid, and a return port formed such that a working fluid return, and the first outlet, the second outlet, and the return port, are adapted to be connected with the one inlet by the operating unit, andwherein the housing is formed in a cylindrical pipe shape of which both ends thereof are opened, and the operating units are mounted at respective sides of the housing to selectively connect the one inlet with the first outlet, the second outlet, or the return port. 2. The valve of claim 1, wherein the deformable member is adapted such that a fixing ring is mounted at the first end thereof, and is fixed to the penetration hole of the flange member in the state of being inserted into the penetration hole of the flange member by the fixing ring. 3. The valve of claim 2, wherein a ring groove is formed along an exterior circumference of the first end of the deformable member such that the deformable member is fixed in the state that the fixing ring is inserted thereto. 4. The valve of claim 1, wherein the deformable member is formed of a wax material which is expanded or contracted in accordance with the temperature of the flowing working fluid. 5. The valve of claim 1, wherein the elastic member is formed as a coil spring of which a first end thereof is supported by a second end of the deformable member in a state of being inserted into the sliding member and a second end thereof being supported by the closed second end of the housing. 6. The valve of claim 1, wherein the end cap is fixed to the housing by a mounting ring which is fixedly mounted at an interior circumference of the opened first end of the housing. 7. The valve of claim 6, wherein the mounting ring is fixedly mounted by a fixing groove which is formed along an interior circumference of the opened first end of the housing. 8. The valve of claim 1, wherein the housing is formed in a cylindrical pipe shape of which a first end thereof is opened and a second end thereof is closed in the length direction, and the operating unit is mounted at the opened first end. 9. The valve of claim 1, wherein one outlet and the one inlet are provided to the housing and are formed at opposite sides of the housing in the length direction, and the outlet side is closed and the inlet side is opened to form a 2-way valve of which the operating unit is mounted to an interior thereof. 10. The valve of claim 1, wherein the one inlet is provided to the housing, the valve is a 3-way valve which has a first outlet and a second outlet disposed with the inlet interposed therebetween and are respectively formed apart at the opposite side to that of the one inlet, and are adapted to be selectively connected with the one inlet by the operating unit. 11. The valve of claim 1, wherein a supporting member is mounted at the center of the housing for supporting each elastic member of the operating unit. 12. The valve of claim 11, wherein a flow hole for flowing the flowing working fluid into the one inlet is formed at the supporting member.
