摘要： A juncture and method for changing direction of fuel flow in a high pressure fuel injection system such as a common rail and/or a fuel pump, the juncture comprising a body, a first passage formed in the body having a first diameter and a longitudinal axis extending therethrough, the first passage including a groove positioned along a portion of the longitudinal axis, and a second passage formed in the body having a second diameter, a central axis extending therethrough, and an opening, the opening of the second passage being provided in the groove of the first passage to allow fluidic communication between the second passage and the first passage so that stresses at the juncture caused by high pressure fuel changing direction of flow is reduced.

摘要： An improved rotary fuel distributor is provided which effectively dynamically centers the rotor during operation while actively cooling the rotor and refilling fuel passages to minimize cavitation. A pressure balancing system is provided which includes pressure area defining grooves formed adjacent a rotor outlet port to control the pressure gradient in the clearance between the rotor and the distributor housing thereby effectively providing a more predictable force component which can be controlled to more effectively balance the rotor in conjunction with two balancing ports positioned on the opposite side of the rotor from the outlet port. A refill and cooling system is provided to continuously and actively cool the rotor with cool, low pressure fuel throughout rotation thereby displacing the hot fuel with cool fuel and effectively preventing thermal seizure of the rotor. The refill and cooling system also includes passages for effectively refilling delivery passages formed in the distributor housing while intermittently refilling supply passages with cool, low pressure fuel after each injection event.
