摘要： Disclosed is an electromagnetic valve in which a force due to a working fluid from an inflow hole acting perpendicularly with respect to the axis of a shut-off valve is reduced to thereby reduce the sliding resistance of the shut-off valve. An electromagnetic valve according to the present invention includes: a housing (10) having an inflow hole (11), an inner flow path (12), and a discharge hole (13); a valve seat (15) secured in position inside the housing (10); a shut-off valve (16) adapted to abut one surface of the valve seat (15) to shut off the working fluid flowing into the inner flow path (12) through the inflow hole (11); and a pressure regulating valve (17) provided coaxially with the shut-off valve (16) and adapted to control, through adjustment of the dimensions of a gap between itself and the other surface of the valve seat (15), the amount of working fluid flowing to the exterior of the housing (10) through the discharge hole (13). In the electromagnetic valve, the housing (10) is equipped with a whirling member for causing the working fluid having flowed into the inner flow path (12) through the inflow hole (11) to whirl in one direction.

摘要： A bleed-type proportional electromagnetic valve having an input port, output port, and ejection port is disclosed. Fluid force and pressing force, proportionate to an output pressure and a current flowing in a solenoid coil respectively, act on a bleed valve for controlling the output pressure, whereby the valve can obtain an output pressure commensurate to the flowing current by displacing the valve to a position that those forces counterbalance, wherein the valve is provided with a stop valve disposed so as to be in sliding contact with a passage between the input and output port, and in contact with or separated from a valve seat. This enable the stop valve to contact with the valve seat so as to close the input port and communicate the output port with the ejection port when controlling the output pressure to be minimum.

摘要： A tappet turning prevention structure for a fuel supply apparatus includes a piston defining a fuel pressurizing chamber within the housing. A tappet disposed at one end of the piston has accommodated in it a roller driven by a cam of an engine and a roller supporting pin for transmitting a force from the cam to the piston. The tappet is housed by a bracket which has one or two grooves in an inner surface of it for supporting the roller supporting pin at one or both ends. The number of parts can be decreased because the turning prevention pin for the tappet and the roller supporting pin is a single common pin, and therefore the need of controlling of the press-fit loads is eliminated because no process for thrusting the tappet turning prevention pin into the outer circumference of the tappet is involved.
