Definitions

  • the door stop releasing angle is predetermined by the control of the opening degree of the stop valve which is adjusted by the adjusting member such as an adjusting bolt. In a case where the door now in a stopped state is closed, the stop valve is released by forcibly pushing the door.
  • the main shaft accommodation portion 1a is closed by a cover member 3 and the main shaft 2 is secured therein to be rotatable by a bearing 4 mounted to the central portion of the cover member 3 and a bearing 5 mounted to the lower surface of the piston accommodation portion 1c.
  • a leaf-shaped cam plate 6 accommodated in a central gap in an operating plate 7 in the main shaft accommodation portion 1a. Rollers 8 and 9 acting as cam followers are disposed at proper positions opposing to the cam plate 6 in the operating plate 7.
  • the righthand end, as viewed, of the operating plate 7 is connected to the lefthand end of a connecting rod 10, which has the righthand end connected to the piston 11 through a connection pin 12.
  • a delayed action (DA) adjusting valve 30 is disposed between the third passage 28 and the fourth passage 29.
  • the delayed action adjusting valve 30 serves to adjust the flow of the hydraulic oil between the first pressure chamber A and the second pressure chamber B by adjusting the opening degree of the fourth passage 29 in accordance with the rotation of the adjusting valve 30.
  • a fifth passage 31 is formed on the left side, as viewed in Fig. 4, of the fourth passage 29 so as to extend in the same direction of the fourth passage 29 and the fifth passage 31 communicates with a sixth passage 32 extending in the longitudinal direction in the thickened wall of the case 1.
  • the sixth passage 32 communicates with a seventh passage 33 extending in the radial direction of the case 1.
