Abstract: A switchable liquid-filled vibration absorbing mount has a stopper device interposed between a first diaphragm and a bottom portion for regulating downward movement of pushing member when a vacuum is introduced into a switching chamber, so that a protrusion of a valve member does not come out of an inner orifice when a vacuum is applied to the switching chamber to move the first diaphragm to a first position opening the orifice.

Abstract: This invention provides a switching type liquid-in vibration isolating device capable of opening/closing an orifice by changing over between the atmospheric and negative pressure in a switching chamber corresponding to shake and idle vibration, respectively.

Abstract: A switchable liquid-filled vibration absorbing mount which is caused to cope with the shaking vibrations and the idle vibrations by opening/closing orifices and which is enabled to hold the stable characteristics for a long time without being troubled by the slackness of the closed state even after the opening/closing actions are repeated. For this vibration absorbing mount, a first mounting fixture (1) and a second mounting fixture (2) are jointed by a vibration absorbing base (3). In this internal space, there are arranged a partition member (4), a first diaphragm (5) and a second diaphragm (6). A main liquid chamber (7) and an auxiliary liquid chamber (8) are caused to communicate by two inner and outer orifices (14) and (13). A balance chamber (9) is defined between the first and second two diaphragms (5) and (6), and a switching chamber (10), into which the atmospheric pressure and a vacuum can be introduced, is defined between the second diaphragm (6) and the second mounting fixture (2).

Abstract: An engine mount includes an inner member and an outer cylinder having a circumferential position around a central axis of the engine mount, the circumferential position being changeable relative to the inner member. A bracket fixed to the inner member supports an engine on the engine mount, the bracket having a circumferential position around the central axis of the engine mount which is changeable relative to the outer cylinder. A stopper of an elastic material is provided on one of the outer cylinder and the inner member, the stopper contacting the other of the outer cylinder and the inner member when a change in length of one of the outer cylinder and the inner member relative to the other exceeds a reference level.
