摘要： PROBLEM TO BE SOLVED: To mold a different hardness composite vibration insulating rubber in one process. SOLUTION: An inner fitment 2 and an outer fitment 4 are put into a mold with runners of two systems, and parting components 7 are disposed at some intervals in the vicinity of the outer fitment 4 connected with the inner fitment 2, and a low hardness rubber material is injected from a runner on the arm section side, while a high hardness rubber material is injected from a runner on the main stopper side. A low hardness arm section 6, a high hardness main stopper section 10 and peripheral rubber 22 connected with edge rubber 20 can be formed simultaneously by the arrangement, and a low hardness rubber section is integrated with a high hardness rubber section through the parting components 7. At the time, rubbers of two different kinds having different harness are separated across the parting components 7 and not mixed each other. The positions of rubber connecting sections of two different kinds having different hardness, therefore, can be determined by the parting components 7, and the composite molding of different hardness rubbers can be completed in one process by the arrangement.

摘要： PURPOSE:To obtain a nonlinear spring characteristic in the case of a fluid charged vibrationproofing device such as the engine mount rubber of a suspension mount rubber for an automobile by providing a membrane part which makes elastic deformation possible according to input vibration on a partition wall for partitioning off a fluid room into two rooms. CONSTITUTION:An engine mount has a No.1 coupling member 1, which is to be mounted on an engine, coupled with a No.2 coupling member 2, which is to be mounted on the body side, through a rubber 3. The No.1 coupling member 1 has a practically airtight space formed in its housing 4 interior where a fluid room is sectioned on the rubber 3 side by a diaphragm 5 for charging incompressive fluid therein and this fluid room is partitioned off into two rooms 7, 8 by a rubber partition wall 6. In this case, the middle section of the rubber partition wall 6 is made a membrane 11 and a push-up part 12 is provided on a part thereof. Thus spring characteristic of membrane 11 is made nonlinear by the push-up part 12 being deformed by having its tip pushed against a partition wall supporting member 14 when the membrane 11 is deformed downwards.

摘要： PROBLEM TO BE SOLVED: To bring the spring characteristics of a membrane part into a nonlinear state. SOLUTION: An almost closed space in a housing 4 is partition by a diaphragm 5 to form a liquid chamber, which is further partitioned into first and second chambers 7 and 8 by a rubber partition wall 6, the first and second chambers being intercommunicated through an orifice passage 9. The intermediate part of the rubber partition wall 6 forms a membrane part 11 a part of which forms a press part 12. When the membrane part 11 is bent and deformed to a position below a figure, the press part 12 is formed such that the tip thereof is pressed against a partition wall support member 14 and deformed, whereby a repulsion force due to deformation is changed into a nonlinear state with the progress of deformation of the membrane part 11 and as a result, the spring characteristics of the membrane part 11 are brought into a nonlinear state.

摘要： PURPOSE: To provide a fluid packing type mount which can adjust the inner pressure and change the length of an orifice. CONSTITUTION: This device has a cylindrical rubber block 3 for connecting a first connecting member 1 attached to an engine to a second connecting member 2 connected to a vehicle body and the rubber block 3 is divided by a separating wall 6 into a first room 8 and a second room 9 which communicate each other through an orifice passageway 34. The orifice passageway 34 communicates with the first room 8 through a middle opening 37 which is opened and closed by a valve 38 changing the length of the passageway and a constantly open end at the end of the passageway. If a part of wall of a cylindrical part 5 of the rubber block 3 is made a movable wall 12 and the pressure of an outer control room 26 is made negative, the inner pressure of the first room 8 is reduced and the valve 38 changing the length of the passageway is moved to open the middle opening 37 and to shorten the length of the orifice, thereby setting the minimum dynamic spring constant in the range of idle vibration, which greatly reduces a dynamic spring constant.

摘要： PURPOSE: To provide a liquid seal mount by which the length of an orifice can be rapidly changed over. CONSTITUTION: A damping orifice 60 arc-shaped and long in plane view and a rectilinear short idle orifice 61 are arranged, and the orifices are connected by a common inlet 32, and also an outlet side is formed in such a way that a first outlet 52 and a second outlet 53 are formed separately from each other, and the second outlet 53 is opened/closed by a valve part 21 integrated with a diaphragm 7. The valve part 21 is opened by the intake negative pressure of an engine during an idling period, however, at this time, the center of the second outlet 53 is shifted from the center of the valve part 21 to a streamline direction in which fluid is led to flow through the idle orifice 61 so that the valve part 21 is slantly opened and the turbulance of fluid flow in the vicinity of the second outlet 53 can be prevented, therefore the characteristics of a liquid seal mount can bee rapidly changed over.
