[0093] Figure 7 It is an explanatory view enlargedly showing the valve body 50 and the valve body supporting portion 460 of the fluid shock absorbing device 10 according to Embodiment 2 of the present invention. In addition, in Figure 7 , shows a state where the spool 50 is in an open posture. In Embodiment 1, the receiving portion 466 formed on the first convex portion 461 receives the entire protruding portion 52 of the valve element 50 when the valve element 50 is in the closed posture. Figure 7 As shown, a gap S may be formed between the receiving portion 466 formed on the first convex portion 461 and the valve body 50 , and in the vicinity of the boundary between the base portion 51 and the protruding portion 52 . Even with such a structure, in the open position, since the inner part 520 of the protruding part 52 of the valve body 50 is formed on the first convex part 461 of the rotary shaft 40 from the first part 521 to the second part 522 of the protruding part 52 ...

[0095] Figure 8 It is an explanatory view enlargedly showing the valve body 50 and the valve body supporting portion 460 of the fluid shock absorber 10 according to Embodiment 3 of the present invention. In addition, in Figure 8 , shows a state where the spool 50 is in an open posture. In Embodiment 1, the entire radially outer end portion 465 of the first protrusion 461 serves as the receiving surface 466a, but in this embodiment, as Figure 8 As shown, a part 465 a of the end portion 465 is located radially inward of the receiving surface 466 a and is separated from the protruding portion 52 . More specifically, a portion 465 a of the end portion 465 that overlaps with the vicinity of the boundary between the base portion 51 and the protruding portion 52 in the second direction B is located radially inward of the receiving surface 466 a and separated from the protruding portion 52 . Even with such a structure, in the open position, the inside portion 520 of the protrudi...

Abstract

The present invention provides a fluid damper device and a machine equipped with the fluid damper device. The fluid damper device can suppress lifting of a valve body from a rotary shaft when a rotor is rotated in the direction of opening. In a damper chamber of this fluid damper device, a protruding part of a valve body protrudes from a base part toward the outside in the radial direction of a rotary shaft, and toward one side (a first direction (A)) around the axial line of the rotary shaft, and a valve body support part of the rotary shaft is equipped with a base part support part between a first protruding part and a second protruding part. An inside portion of the protruding part of the valve body has a first portion and a second portion separated from each other in the direction in which the protruding part protrudes, and when the valve body is in the open position this first portion and second portion are supported by a seat part formed on the first protruding part of the rotary shaft. Therefore, even when the valve body is subjected to fluid pressure in the first direction, a situation in which the valve body rotates with the point of contact with the first protruding part as a fulcrum does not easily occur.

Description

technical field [0001] The invention relates to a fluid buffer device filled with fluid between a casing and a rotor and equipment with buffer. Background technique [0002] In the fluid damper device in which fluid is filled between the casing and the rotor, the rotating shaft of the rotor is arranged inside the bottomed cylindrical casing, and the spool is arranged on the rotating shaft. Then, when the rotary shaft rotates in the first direction and the spool is in the closed state, since the fluid tends to be compressed, a load is applied to the rotary shaft. On the other hand, when the rotation shaft is reversed in the second direction and the valve element is in the open state, no load is applied to the rotation shaft because the fluid passes through (see Patent Document 1). [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2010-151306 [0004] In this fluid cushioning device, as shown in FIG. 12( a ), the inventors of the present application stud...
