Problems solved by technology

[0005] However, in the prior art described above, the emergency safety mechanism 62 is constituted by the rupture plate 61d provided on a part of the circumference of the peripheral surface (cylindrical portion 61a) of the support member 61 as described above. Therefore, the rupture pressure Higher (requires greater pressure to the extent that the metal plate is broken), so there is a defect that the safety mechanism 62 does not operate in an emergency if a relatively high high pressure is not reached
In addition, in order to provide the rupture plate 61d on a part of the circumference of the support member 61 (cylindrical portion 61a), it is necessary to press the support member 61 and then perform cutting processing, so that the production cost of the support member 61 is relatively high. The pitfalls of extra effort and time

Embodiment

[0082] Embodiments of the present invention will be described below with reference to the drawings.

no. 1 example …

[0084] figure 1 The accumulator 1 according to the first embodiment of the present invention is shown. The accumulator 1 according to this embodiment is a metal bellows type accumulator using a metal bellows as the bellows 10, and is configured as follows.

[0085] That is, an accumulator case 2 having an oil port 3 connected to a pressure pipe (not shown) at one end (lower end in the figure) and a gas sealing port 4 at the other end (upper end in the figure) is provided. A bellows 10 and a bellows cover 11 are arranged inside the housing 2, and the inside of the housing 2 is divided into a gas chamber 12 filled with high-pressure gas (for example, nitrogen gas) and a liquid chamber 13 connected to the oil port 3 . As the case 2, a case composed of a combination of a bottomed cylindrical case 5 and an end cap 6 fixed (welded) to one end opening (the upper end opening in the figure) of the case 5 is shown, However, the component distribution structure of the housing 2 is not...

Abstract

The present invention provides an accumulator provided with an emergency safety mechanism that can be used at a lower cost than the case where a rupture plate is provided on a part of the circumference of the support member. Action under pressure. In order to achieve this object, the accumulator of the present invention has an emergency safety mechanism that releases the pressure inside the case to the Emergency release on oil port side. The emergency safety mechanism communicates the liquid chamber with the oil port through the first pressure release flow path and the second pressure release flow path, wherein the first pressure release flow path is supported by a sealing member provided with a part of the circumference. The frame is formed on the supporting surface; the second pressure release flow path is formed by the disappearance of the rubber-like elastic body of the seal due to high temperature.

Description

technical field [0001] The invention relates to an accumulator used as a pressure accumulator or a pulsation pressure attenuation device. The accumulator of the present invention is used, for example, in a hydraulic system for automobiles or a hydraulic system for industrial equipment. Background technique [0002] Since before, as Figure 10 As shown, there is known an accumulator 51 having a structure including an oil port 53 connected to a pressure pipe (not shown) and a gas sealing port 54 via a bellows 55 and a bellows cover 56 The inner space of the casing 52 is divided into an air chamber 57 filled with gas and a liquid chamber 58 connected to the oil port 53. The bellows cover 56 moves and the bellows 55 expands and contracts in such a way that the gas pressure and the liquid pressure are balanced, thereby performing Accumulation operation or pulsation pressure damping operation (refer to Patent Document 1). [0003] In addition, the accumulator 51 is provided with...
