According to three kinds of situation (promptly open the door, close the door lentamente and close the door at full tilt) of operation, describe the operation of damper 500 in detail with reference to accompanying drawing 14 to 16 below.

The situation of 1) opening the door:

When opening the door, the damper 500 that inserts adapter 200 moves forward, to get back to the home position through spring 112.In the process of opening the door, the oil in main body 100 partly flows into the AA part from BB.

The oil of BB part passes the housing oil hole 130d of sponge case 130, the oil hole 124e of piston holder 124 and the oil hole 120b of piston 120 and flows into the AA part.

When piston 120 motion through main body 100 arrives the control oil groove 114 of spring guide 110, flow directly into oil hole 124e through control oil groove 114 at the oil of AA part.

The situation of 2) closing the door lentamente

When door was closed lentamente, hinged operation part 312 promoted hinge guide stopper 102.

Therefore, damper 500 is inserted in the adaptor body 230.Correspondingly, bar 160 is inserted into the inside of damper 500, and oil partly flows into the BB part from AA.

Oil in the AA part flows through the oil hole 102 that is formed at piston 120 middle parts along oil duct groove 124c.Then, oil flow to sponge 132 through the housing oil hole 130d of sponge case 130.Then, oil flows into oil hole 124e through the oil duct control flume 114 of spring guide 110.

Because the motion of main body 100 when arriving the oil duct control flume 114 of spring guide 110, the mobile of oil of the oil duct control flume 114 through spring guide 110 closed when piston 120.That is, oil only flows through the access opening 120b that is formed at piston 120 middle parts.Oil duct forms deceleration part like this.That is, the flow of oil reduces, and shuts door reposefully at that moment with what close fully at door.

The situation of 3) closing the door at full tilt

When firmly at closing time, hinged operation part 312 has impacts ground promotion hinge guide stopper 102, and damper 500 inserts adaptor bodies 230.At this moment, bar 160 also inserts the inside of damper 500, and oil partly flows into the BB part from AA.

The flowing phase of the mobile and oil under the situation of slowly closing the door of oil together.Yet if apply bigger impact, the outer surface of the access opening 120b of piston 120 can closely adhere to passage control oil groove 124d under the effect of inertia force, shown in the dashed circle C among Figure 14.Therefore, the inlet of access opening 120b narrows down, and correspondingly, through the predetermined portions of blocking channel groove 124c, makes the flow of oil diminish suddenly.

Identical with the situation of slowly closing the door, in control oil groove 14 ends (being deceleration part) that piston 120 arrives spring guides 110 afterwards, the amount of the oil that flows reduces, slowly to close the door.

Damper 500 can form the rectangle with bevel angle, to widen the size that absorbs the piston that impacts.The damper 500 of this rectangular shape with fillet absorbs three times or repeatedly bigger than circular damper 500 impact.And the damper of rectangular shape is easier to make than circular damper.
