摘要： It is an object of the present invention to to eliminate a valve holder and accommodate a valve guide in a small space provided between a valve seat and a peripheral surface part of a pressure chamber to thereby bring a pump into less size. In order to achieve the above object, the valve guide SG which guides a stroke of a valve 203 is provided inside the valve seat 214S. Specifically, a valve 203 includes an annular abutting surface 203R that abuts a valve seat 214S formed in a valve housing 214 to shut off a fuel intake passage and a bottomed cylindrical part 203F, 203H provided at an inner peripheral part of the annular abutting surface 203R. The bottomed cylindrical part 203F, 203H is inserted into a fuel introduction hole 214P formed in the valve housing 214 inside the valve seat 214S. A member having a cylindrical surface part which supports a reciprocating motion of the valve 203, is fixed to the valve housing 214, in face-to-face with an inner peripheral part of the bottomed cylindrical part 203F, 203H. Thus, the size of the valve guide SG that protrudes from the surface of the valve seat 214S to the pressure chamber side can be shortened. It is therefore possible to bring an inlet valve mechanism portion into less size and eventually render the pump in a small size.

摘要： It is an object of the present invention to improve responsiveness in valve opening and valve closing of an electromagnetically-driven intake valve unit (200) in which a valve (203) is provided on a pressurizing chamber side of a valve seat (214S). The valve includes an annular abutting surface (203R) that abuts the valve seat (214S) to shut off a fuel intake passage and a bottomed cylindrical part (203F,203H) provided at an inner peripheral part of the annular abutting surface (203R). The bottomed cylindrical part (203F,203H) is inserted into a fuel introduction hole (214P) formed in the valve housing (214) inside the valve seat (214S), and the outer surface of an end part of the bottomed cylindrical part (203F,203H) is exposed to fuel in a low pressure fuel chamber (10A) provided upstream of the fuel introduction hole (214P). Thus, a low pressure is less produced upstream of the valve seat (214S) and thereby a static or dynamic fluid force of the fluid for biasing the valve (203) toward the valve opening direction is exerted on the entire outer surface of the valve (203), so that it is possible to provide a fast and stable valve opening speed of the valve (203).

摘要： The invention relates to a method for regulating a common-rail injector. Said method encompasses the detection of a signal (S) from a sensor, which signal is proportional to a pressure in a valve chamber of the common-rail injector, the evaluation of a change in the signal (S) over time (t) in order to detect at least one operation event of the common-rail injector, and the variation of at least one operating variable of the common-rail injector in a manner dependent on the at least one operation event, wherein the at least one operating variable is selected from an opening duration, a closing duration, an opening time and a closing time of a switching valve of the common-rail injector, and from an opening duration, an opening time and a closing time of a needle valve of the common-rail injector.
