Abstract
Abstract A fluid-selaed engine mounting has a connector (20, 120, 220, 420) adapted to be connected to an engine, a base (10, 110, 210, 310, 410) adapted to be connected to a vehicle frame, an elastic member (30, 130, 230, 330, 430: 40, 140, 240, 340, 440) between the connector and the base and elastically deformable in response to vibrations transmitted thereto, the base, and the elastic member jointly defining a fluid chamber (2,102, 202, 302, 402: 3, 103, 203, 303, 403) in which a fluid is sealed, and a partition (50, 150,250,350,450) dividing the fluid chamber into a first chamber (2, 102, 202, 302, 402) adjacent to the connector and a second chamber (3, 103, 203, 303, 403) adjacent to the base, the partition (50, 150, 250, 350, 450) having an orifice (51, 151, 251, 351, 452a, 453a) through which the first and second chambers communicate with each other. The engine mounting also includes a diaphragm (60, 160, 260) mounted on the base or the connector for varying the volume of one of the first and second chambers when vibrations are transmitted to the engine mounting.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
144 words
A fluid-sealed engine mounting for mounting an engine on a vehicle frame, comprising: (a) a connector adapted to be connected to the engine; (b) a base adapted to be connected to the vehicle frame; (c) an elastic member joined between said connector and said base and elastically deformable in response to vibrations transmitted thereto, said connector, said base, and said elastic member jointly defining a fluid chamber in which a fluid is sealed; (d) a partition dividing said fluid chamber into a first chamber adjacent to said connector and a second chamber adjacebt to said base, said partition having an orifice through which said first and second chambers communicate with each other; and (e) a diaphragm.mounted on one of said connector and said base for varying the volume of one of said first and second chambers when vibrations are transmitted to the engine mounting.
Claim 2
Dependent Claim
144 words
A fluid-sealed engine mounting for mounting an engine on a vehicle frame, comprising: (a) a connector adapted to be connected to the engine; (b) a base adapted to be connected to the vehicle frame; (c) an elastic member joined between said connector and said base and elastically deformable in response to vibrations transmitted thereto, said connector, said base, and said elastic member jointly defining a fluid chamber in which a fluid is sealed; (d) a partition dividing said fluid chamber into a first chamber adjacent to said connector and a second chamber adjacebt to said base, said partition having an orifice through which said first and second chambers communicate with each other; and (e) a diaphragm.mounted on one of said connector and said base for varying the volume of one of said first and second chambers when vibrations are transmitted to the engine mounting.
Claim 3
Dependent Claim
45 words
A fluid-sealed engine mounting according to claim 1, wherein said base comprises a frustoconical tubular body mounted on an end of said elastic member and having a radially outwardly projecting flange on one end thereof closely to said connector for attachment to the vehicle frame.
Claim 4
Dependent Claim
57 words
A fluid-sealed engine mounting according to claim 1, wherein said elastic member has a first portion defining a portion of said first chamber and a second portion defining a portion of said second chamber, said partition comprising a plate joined between said first and second portions of said elastic member, said diaphragm being mounted on said base.
Claim 5
Dependent Claim
40 words
A fluid-sealed engine mounting according to claim 3, wherein said first and second portions of said elastic member have respective holes having substantially the same diameter as that of said orifice in said partition and disposed concentrically with said orifice.
Claim 6
Dependent Claim
16 words
A fluid-sealed engine mounting according to claim 1, wherein said diaphragm is mounted on said connector.
Claim 7
Dependent Claim
44 words
A fluid-sealed engine mounting according to claim 5, wherein said base comprises a frustoconical tubular body mounted on an end of said elastic'member and having a radially outwardly projecting flange on one end thereof remotely from said connector for attachment to the vehicle frame.
Claim 8
Dependent Claim
42 words
