摘要： The invention relates to an electromagnetically actuable intake valve for a high-pressure pump of a fuel injection system, in particular of a common-rail injection system, comprising a reciprocating valve closure element (2) that engages with a valve seat (1) and is loaded in the closing direction by the spring force of a valve spring (3) which is supported on a spring plate (4) connected to the valve closure element (2), further comprising a reciprocating armature (6) that engages with an electromagnet (5) and is loaded in the direction of the valve closure element (2) by the spring force of an armature spring (7) which is larger than that of the valve spring (3). According to the invention, the spring plate (4) has a first abutment face (9) for limiting the opening travel of the valve closure element (2) and a second abutment face (10) for mechanically coupling to the armature (6). The invention also relates to a high-pressure pump having such an intake valve.

摘要： A valve seat has an inner passage and outer passages. A suction valve member has first passages and a first projection portion that guides, to the first passages, the fuel that flows from a pressure chamber at the time of valve opening. Therefore, an action force by the dynamic pressure applied to the suction valve member in the valve closing direction is reduced. An action force by the pressure of fuel that flows into pressure equalization grooves counterbalances the action force by the dynamic pressure of the suction valve member. Therefore, self-closing by the dynamic pressure can be inhibited, and the maximum output of an electromagnetic driving unit can be reduced. Fuel flow through a passage radially outside the suction valve member and the firs passages. A fluid passage area is securable even when a lift amount of the suction valve member is small.

摘要： A fuel system includes a plurality of fuel injectors each defining a nozzle supply passage, a nozzle outlet, a low pressure space, and a drain. The fuel system includes a plurality of mechanically actuated pressure intensifiers each including a tappet and being positioned partially within one of the fuel injectors, and a common rail fluidly connecting with each of the fuel injectors. Each of the fuel injectors further includes an injection pressure control mechanism having an injection pressure control valve. Each injection pressure control valve blocks the corresponding pressure intensifier from the common rail and fluidly connects the pressure intensifier with the low pressure space at a first position, and fluidly connects the pressure intensifier with the common rail and blocks the pressure intensifier from the low pressure space at a second position. Each of the fuel injectors further includes a pressure recovery mechanism having a pressure recovery valve. Each pressure recovery valve blocks the corresponding pressure intensifier from the common rail and fluidly connects the low pressure space and the drain at the first position, and fluidly connects the low pressure space with the common rail and blocks the low pressure space from the drain at the second position. Injecting fuel via operating the fuel system may include operating the fuel system in a low leakage mode where the pressure intensifier displaces fuel at a low pressure, between high pressure injections.

摘要： The objective of the present invention is to dampen operating sounds of an electromagnetic drive mechanism used for a variable displacement to reduce an individual difference depending on apparatus due to the control mechanism in a high-pressure fuel supply pump change over time or installation tolerance.To achieve the above objective, the present invention is configured such that before the electromagnetic drive mechanism supplies a drive force to a plunger which is electromagnetically driven by the electromagnetic drive mechanism, another displacement force situates the plunger in a specific position. When compared to an occasion where the plunger is displaced all strokes by a magnetic biasing force, the above configuration is able to reduce the force of impact on a member (for example, valve body) mounted to the plunger and a restricting member, thereby damping the collision noise. Furthermore, since an extra member, such as a damping member, is not required, individual difference depending on apparatus do not easily occur.

摘要： An electrically controlled fuel injector includes an armature that is movable between a first armature position and a second armature position inside an armature cavity containing fuel. By reducing the size of the armature cavity to a squish film drag gap, the armature experiences a squish film drag phenomenon when the armature moves from the first armature position to the second armature position reducing the armature travel speed but also reducing the settling time of the armature after an injection event. By reducing the armature travel speed; the armature experiences a reduction in magnitude of armature bounce allowing the armature to settle down quicker and produce minimum controllable injection events with shorter dwell times than predecessor fuel injectors, especially for close coupled post injection events.

摘要： A pump includes a cylinder formed with a plunger chamber, a low-pressure portion, to which low-pressure fuel is supplied, a plunger reciprocating in the cylinder to pressurize fluid in the chamber, which is drawn from the portion, and a magnet valve having a valve body. A low-pressure passage communicates between the chamber and the portion. The magnet valve blocks the passage with the valve body when energized, to control timing, with which fluid in the chamber starts to be pressurized by the plunger. Dynamic pressure of fluid flowing from the chamber into the passage is applied to the valve body in a direction in which the valve body closes the passage. The valve body includes an inclined surface at a portion of the valve body, to which the dynamic pressure is applied. The surface is nonparallel to a plane, which is perpendicular to a displacement direction of the valve body.

摘要： An injector for controlling fluids has a piezoelectric actuator and a hydraulic pressure intensifier. The hydraulic pressure intensifier is composed of a first piston, a second piston and a pressure chamber filled with fluid and situated between the two pistons. In addition, a control valve and a priming device are provided to replace the fluid loss in the pressure chamber caused by leakage. The priming device has a priming chamber filled with fluid, and leakage losses in the pressure chamber are replaced by fluid from the priming chamber during a return movement of the hydraulic pressure intensifier as a result of a displacement effect in the priming chamber created directly or indirectly by the first piston.
