Abstract: The filter device includes a case, an element, and a water separator. The case accommodates the element and the water separator. The element removes solid particulates from the fuel. The element can be replaced by opening the case. The water separator removes water content from the fuel. The water separator is held in the case. The water separator is movable relative to the case. The water separator is movable within a movable range. The element and the water separator are provided with a passage connecting member for connecting a fuel passages.

Abstract: A pulsation damper for use in an automotive fuel supply system is provided which consists of a casing, a diaphragm, and a cover. The cover is joined to the casing with the diaphragm nipped therebetween. The pulsation damper also includes a supporting member secured to a central portion of the diaphragm to support the diaphragm physically. The supporting member has a protrusion fitted in a recess formed in the casing to hold the supporting member from moving in an unwanted direction, thereby ensuring coaxial alignment of the diaphragm with the casing when the cover is joined to the casing. The protrusion may alternatively be formed on the casing, while the recess may be formed in the supporting member.

Abstract: A vibration isolator designed to improve mounting facility is disposed between a vibration source and a base on which the vibration source is supported. The vibration isolator has an elastic member provided between the vibration source and the base to elastically support the vibration source, a main chamber in which a fluid is enclosed and the volume of which is changed according to a deformation of the elastic member, a sub chamber defined by an elastic membrane and communicating with the main chamber through an orifice, a moving member provided in a fluid chamber formed by the main and sub chambers, and an actuator for driving the moving member. The actuator is fixed to the elastic membrane in a fluid sealing manner, and drives the moving member from the outside of the fluid chamber formed by the main and sub chambers through attachment members connected to the moving member.
