摘要： A high pressure fuel supply pump which is driven by a cam connected to an engine is composed of a cylinder, a plunger slidably disposed in the cylinder, a tappet linked to the cam, a coil spring biasing the tappet against the cam, a cylindrical guide for the tappet, a plate member in abutment with head portion of the plunger, and a plurality of balls disposed between the plate member and the tappet to be slidable in directions perpendicular to the reciprocating motion of the plunger. Each of the balls shares the stress applied from the tappet.

摘要： A fuel supply system includes a fuel pump, a filter element, a pressure regulating valve, and a filter case. The filter case is configured to cover radially inner and outer surfaces of the filter element. The filter case has a receiving portion. A bottom portion of the receiving portion and an end portion of the filter element defines therebetween an outflow chamber for storing fuel. The outflow chamber includes a partitioning member that partitions the outflow chamber into first and second outflow chamber sections. The second outflow chamber section is communicated with an inlet portion of the pressure regulating valve. The partitioning member has a communication portion that provides communication between the first and second outflow chamber sections.

摘要： A fuel supply device includes a subtank in a fuel tank, a fuel pump in the subtank having a first pump unit suctioning fuel in the subtank to supply fuel to an external equipment and a second pump unit suctioning fuel outside the subtank to pump fuel into the subtank, and a filter connected to a first suction port of the first unit and a second suction port of the second unit and filtering supply fuel supplied to the equipment and pump fuel pumped into the subtank. The filter includes a case, a first filter, and a second filter. The first filter in a first passage of the case directing fuel in the subtank into the first port filters the supply fuel. The second filter in a second passage of the case directing fuel outside the subtank into the second port filters the pump fuel.
