  • Interior structures of each of the lower bearing accommodating section 16 and the upper bearing accommodating section 17 are not illustrated in the drawing, but they are constituted in the same manner as the bearing accommodating sections 16 and 17 in the first embodiment.
  • valve 28 is fixed to the shaft 18 by the same manner as that of the valve 28 of the first embodiment.
  • the valve 28 is a butterfly valve.
  • the valve 28 assumes two rotation positions. Depending upon the rotation positions, one of a first mode which brings the ports 12 and 13 into communication with each other and brings the ports 14 and 15 into communication with each other, and a second mode which brings the ports 12 and 15 into communication with each other and brings the ports 13 and 14 into communication with each other is selected.
  • a cross section of the body 2 is formed into substantially T-shape in the vicinity of the case 11 as viewed from above.
  • the body 2 is of an upper and lower two body structure comprising a mating surface 44 of an upper half body 43 and a mating surface 46 of a lower half body 45, and the mating surface 44 and the mating surface 46 are superposed and welded to each other, thereby integrally forming the body 2.
  • Each of the upper half body 43 and lower half body 45 is made of thin metal or thin compact.
  • the case 11 is fixed to and disposed in a central portion 47 of the body 2.
  • the body 2 includes three fluid passages 48, 49 and 50 extending in three directions from the central portion 47.
  • the fluid passages 48, 49 and 50 are respectively in communication with the corresponding ports 12, 13 and 14 of the case 11.
  • the port 15 is occluded by an occluding wall 64 of the body 2.
  • the upper and lower ends of the central portion 47 of the body 2 respectively include short cylindrical sections 52 and 53.
  • the upper bearing accommodating section 17 upwardly projects from the upper cylindrical section 52, and a gap between the outer peripheral surface 54 of the bearing accommodating section 17 and the upper end surface 55 of the cylindrical section 52 is occluded by welding.
  • the lower bearing accommodating section 16 downwardly projects from the lower cylindrical section 53, and a gap between the outer peripheral surface 56 of the bearing accommodating section 16 and the lower end surface 57 of the cylindrical section 53 is occluded by welding.
  • the upper end 22 of the shaft 18 is connected to a lever 58 (Fig.2) which is rotated and operated by a driving mechanism (not shown) as in the first embodiment.
  • the fluid passage of the body 2 may be curved.
  • the valve apparatus When the valve 28 is in the rotation position shown in Fig.8, the valve apparatus having the above-described structure maintains the communication state between the ports 12 and 13, and between the ports 14 and 15, and maintains the non-communication state between the ports 12, 13 and the ports 14, 15. However, since the port 15 is always closed, the ports 12 and 13 are maintained in their communicated state, and the ports 12, 13 and 14 are maintained in their non-communicated state. From this state, if the lever 58 is rotated and operated and the valve 28 assumes the other rotation position, the ports 13 and 14 are brought into communication with each other, and the ports 12, 13 and 14 are brought into non-communication state. Thereafter, if the lever 58 is rotated and operated in the opposite direction from the former rotating and operating direction, the valve 28 is again returned to the rotation position shown in Fig.8.
  • the valve apparatus of the embodiment includes the case 11 for accommodating the valve 28, and the body 2 forming the fluid passage as separate constituent elements, and the case 11 is fixed and disposed in the body 2. Therefore, the case 11 is made of casting and the body 2 is made of metal so that the apparatus is reduced in weight, and the rigidity of the main portion, i.e., of the peripheries of the valve can be secured, and the hermeticity of the valve 28 can be secured.
  • the four-way valve can be formed by combining the case 11 and the body 2 having the fluid passages 48, 49, 50 and 51 corresponding to the four ports 12, 13, 14 and 15, and the three-way valve can be formed by combining the case 11 and the body 2 having the fluid passages 48, 49 and 50 corresponding to the three ports 12, 13 and 14. Therefore, the case 11 can be used as a common part.
  • the butterfly valve is used as the valve 28, and the sealing structures 31 to 34 are formed on abutment positions between the outer peripheral edge 30 of the butterfly valve 28 and the butterfly valve 28 of the case 11, the hermeticity of the valve 28 can be secured.
