The present invention relates to a high-pressure fuel supplying pump, comprising: a barrel (1) formed with a fuel feeding port (1a), a plunger hole (1b) and a receiving chamber (1c) which communicate with each other; and a plunger (2) which is able to reci...

The present invention provides a fuel injection pump which pressurizes and discharges fuel that is drawn in a low-pressure state, the fuel injection pump including a pump housing having a valve holder in which an inlet valve, an outlet valve, and a relief ...

An outlet valve assembly for a common rail fuel pump for an internal combustion engine, comprising a valve member (18) provided with a frusto-conical surface which is engageable with a valve seating (16) to control fuel flow between a high pressure pump vo...

The pressure control valve system (100) has a main fuel line (103) which is closed with a spring-loaded sealing structure (105) for maintaining a fuel pressure in a fuel line (101). The sealing structure is comprised of a sealing structure head (107) for s...

The valve assembly has two valves arranged concentrically with respect to a common longitudinal axis (A). The former valve is formed as an inlet valve (1) and the latter valve is formed as an outlet valve (2). A pump working space (3) is connected with low...

A high-pressure fuel supply pump mounted with a discharge valve that can reduce an influence of noise caused by a valve body-circumferential flow and a discharge valve unit used therein. The high-pressure fuel supply pump includes a discharge valve (8) whi...

A valve arrangement (32) for controlling fluid flow comprising a valve housing (18) defining a chamber (28) and a conduit (24) wherein a seating region (26) is defined at a transition between the chamber (28) and the conduit (24), a valve member (34) engag...

In connection with a fuel injection device for internal combustion engines, a valve unit is proposed which is located in the transition between pump working chamber, high-pressure accumulator and low-pressure source and which comprises a check piston and a...
