Abstract: A working sheath tube (1) is used when a renovating operation of a pump-discharge pipe (4) branched from a peripheral wall (33) of a tubular barrel (3) inserted into a tank (2) in which a fuel is retained. The working sheath tube has a bottomed tubular shape which can be inserted into the barrel, and has a working space thereinside. A insertion hole (15a) into which a closing member (7) for closing a pump-discharge pipe is inserted is provided on and penetrates a sheath tube peripheral wall (15). While the sheath tube is inserted into the barrel, the insertion hole faces an opening of the pump-discharge pipe.

Abstract: A fluid-filled vibroisolating device includes a joint member adapted to be joined to a vibrating body such as an engine, a support member adapted to be supported on a supporting body such as a vehicle frame and defining an expandable and contractible auxiliary fluid chamber filled with a fluid, an elastomeric member interconnecting the joint and support members and disposed in a vibrating direction in which the vibrating body vibrating direction in which the vibrating body vibrates, the elastomeric member, the joint member, and the support member jointly defining an expandable and contractible main fluid chamber filled with a fluid, a partition mounted in the support member and separating the main and auxiliary fluid chambers from each other, the partition having flow regulator for regulating the flow of the fluid between the main and auxiliary fluid chambers, and a reinforcing member integrally formed with the elastomeric member for preventing the elastomeric member from being collapsed.

Abstract: A hydraulically damped mount includes a mounting element fixed to a moving component and a support fixed to a stationary component. A resilient element is connected between the mounting element and the support and cooperates with a diaphragm to define a fluid chamber. The fluid chamber is divided into a working chamber and a compensation chamber by a partition assembly. The partition assembly has an upper plate and a lower plate joined together to define a space within which a movable plate is vertically movable to absorb movement of the fluid caused by a change in pressure in the working chamber. A spacer is centrally disposed in the upper and lower plates to provide a constant distance therebetween.

Abstract: A fluid-filled vibroisolating device comprises a joint member adapted to be joined to a vibrating body such as an engine. A support member is adapted to be supported on a supporting body such as a vehicle frame and defining an expandable and contractible auxiliary fluid chamber filled with a fluid. An elastomeric member interconnects the joint and support members and is disposed in a vibrating direction in which the vibrating body vibrates. The elastomeric member, the joint member, and the support member jointly define an expandable and contractible main fluid chamber filled with a fluid. A partition is mounted in the support member and separates the main and auxiliary fluid chambers from each other. The partition has flow regulators for regulating the flow of the fluid between the main and auxiliary fluid chamber. A reinforcing member is integrally formed with the elastomeric member for preventing the elastomeric member from being collapsed.

Abstract: A combination viscous and resilient type of mount comprises a rigid boss adapted to be connected to a moving component such as an reciprocating engine, an annular flange adapted to be connected to a stationary support, a resilient element connected between the boss and the annular flange to resiliently supporting the moving component relative to the stationary support, the resilient element having a frustconical shape, a deformable element cooperating with the resilient element to define a chamber for viscous fluid, and a rigid partition connected to the flange and adapted to divide the fluid chamber into a working chamber and a compensation chamber, the partition including at least one orifice through which the two chambers are communicated with each other. A rigid spacer is interposed between the boss and a flange of the moving component and has an annular projection. A rigid ring is inserted into the resilient element and has an outwardly extending annular flange.
