摘要： A two stage intensifier capable of multiple intensification rates comprises a stepped top portion and a shoulder portion, each being actuated by separate fluid passages. A stepped top portion is received into an upper bore of a piston bore and a shoulder is received into a lower bore. The stepped top forms a seal with the upper bore to prevent direct fluid communication between a first actuation cavity above the stepped top and a second actuation cavity above the shoulder.

A plunger (40) is arranged on an axis of a solenoid (47) for axial movement, and a body (41) with the plunger (40) slidably received therein is fixedly arranged in a housing (44). A valve seat (42) is arranged in opposition to one end of the plunger (40) in such a manner that the one end of the plunger (40) is moved to contact with and separate from the valve seat (42). The plunger (40) is urged toward the valve seat (42) by means of a spring (48). The body (41) is formed with an engagement groove (50), into which a caulking portion (51), which is formed by bending or flexing the one end of the housing (44), is engaged to integrally couple the body (41) and the housing (44) with each other.

摘要： A high-pressure fuel supply system can reduce collision sounds generated when a plunger collides with a stopper. An electromagnetic valve includes a plunger, a valve seat with which the plunger is moved into and out of contact so that the valve seat is placed into communication with a pressurization chamber when the plunger is moved apart from the valve seat, a stopper for limiting the separation of the plunger from the valve seat, an armature made of a magnetic material and fixedly secured to the plunger, a core arranged in opposition to the armature, a solenoid wound around the core for attracting the armature toward the core through an electromagnetic force when energized, and a spring for urging the plunger toward the valve seat. A groove is formed near opposed surfaces of the armature and core for magnetically saturating a portion of a magnetic circuit generated by energizing the solenoid.

摘要： A lift-controlled valve as a fuel metering device of an injection system for internal combustion engines has a valve needle which may be actuated axially against the resistance of a spring, the valve needle being situated in a graduated coaxial recess in a valve body and interacting with a valve seat formed in the recess of the valve body in this case controlling the fuel injection process; the valve has in addition a high-pressure area which is connected to an assigned injection nozzle and which is located upstream from the valve seat, a low-pressure area which is located downstream from the valve seat and which opens out into a fuel return flow, and a low-pressure equalizing piston which coaxially adjoins the valve and which is fixedly connected to the valve needle. The characterizing feature is that a first control edge is formed on the low-pressure equalizing piston, the control edge interacting with a second control edge on the valve body recess in the area of the fuel return flow or in such a way that a throttle cross-section which is dependent on the valve lift is formed between the two control edges.

摘要： An oil activated fuel injector control valve which reduces bouncing of the spool and an impact of the spool on an open coil. This eliminates shot by shot variations in the fuel injector as well as increasing the efficiency of the fuel injector. The fuel injector includes a valve control body which has a vent holes which prevent air from mixing with the working fluid. In this manner, the working fluid does not have to compress and/or dissolve the air in the working ports prior to acting on the piston and plunger mechanism in an intensifier body of the fuel injector.
