Abstract
Abstract An engine mount device (20) comprising first and second base plate members (22, 24) which are spaced from each other; an elastic block (26) securely interposed between the first and second base plate members and formed with cavity (28); a partition wall member (32) connected to the first base plate member and including a projecting section (32b, 32c) which projects into and is located within the elastic block cavity (28), the partition wall member defining within the elastic block cavity (28) a fluid chamber (34) to be filled with a fluid and being formed with an orifice (36); and a diaphragm member (38) connected to the partition wall member and including a projecting section (38b, 38c) which projects into and is located within the elastic block cavity, said diaphragm member defining between it and the partition wall member an auxiliary chamber (40) which communicates with the fluid chamber through the partition wall member orifice, a major part of the auxiliary chamber (40) being located with the elastic block cavity, thereby saving the amount of the fluid used in the device (20).

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
187 words
An engine mount device (20) comprising: first and second base plate members (22,24) which are spaced from each other; a block (26) made of elastic material, securely interposed between said first and second base plate members and formed with a cavity (28); a partition wall member (32) connected to said first base plate member and including a projecting section (32b,32c) which projects into and is located within said cavity of said elastic block, said partition wall member defining within said cavity (28) of said elastic block a fluid chamber (34) to be filled with a fluid, said partition wall member being formed with an orifice (36); and a diaphragm member (38) connected to said partition wall member and including a projecting section (38b,38c) which projects into and is located within said cavity (28) of said elastic block, said diaphragm member defining between it and said partition wall member an auxiliary chamber (40) which communicates with said fluid chamber through said partition wall member orifice, a major part of said auxiliary chamber (40) being located within said cavity (28) of said elastic block. (Fig.s 2, 3 & 4)
Claim 2
Dependent Claim
187 words
An engine mount device (20) comprising: first and second base plate members (22,24) which are spaced from each other; a block (26) made of elastic material, securely interposed between said first and second base plate members and formed with a cavity (28); a partition wall member (32) connected to said first base plate member and including a projecting section (32b,32c) which projects into and is located within said cavity of said elastic block, said partition wall member defining within said cavity (28) of said elastic block a fluid chamber (34) to be filled with a fluid, said partition wall member being formed with an orifice (36); and a diaphragm member (38) connected to said partition wall member and including a projecting section (38b,38c) which projects into and is located within said cavity (28) of said elastic block, said diaphragm member defining between it and said partition wall member an auxiliary chamber (40) which communicates with said fluid chamber through said partition wall member orifice, a major part of said auxiliary chamber (40) being located within said cavity (28) of said elastic block.
