Definitions

  • the present invention relates to a high-pressure fuel pump for an internal combustion diesel engine.
  • the present invention relates to a high-pressure fuel piston pump for feeding fuel to a common rail of an internal combustion diesel engine.
  • a high-pressure fuel pump of this type generally comprises a pump housing; a fuel delivery duct; and a delivery valve, which extends along a longitudinal axis along the delivery duct, and comprises a valve seat directly machined in the pump housing; a shutter movable between a closed and an open position in the valve seat; a fastening member suitable for being fastened to the pump housing, and a helical spring suitable for biasing the shutter in the closed position.
  • the helical spring is cyclically compressed between the fastening member and the shutter along the above-identified longitudinal axis and cyclically abuts the shutter against a given portion of the valve seat for closing the delivery valve.
  • the delivery valve allows the fuel flowing along the delivery duct when the fuel pressure in the delivery duct upstream of the delivery valve reaches a level capable of exerting a force on the shutter higher than the sum of the force exerted by the fuel pressure within the delivery duct downstream of the delivery valve and of the force of the helical spring acting on the shutter.
  • the delivery valve opens and closes at each stroke of the piston.
  • the shutter is generally made of hard material and the high number of shocks wears out the portion of valve seat in abutment with the shutter.
  • valve seat Since the valve seat is directly machined in the pump housing, when the portion of valve seat is irreparably worn out the entire high-pressure fuel pump has to be replaced.
  • a know type of valve used in an fuel injector is disclosed in document GB 521,060 , however this type of valve is unsuitable to operate in a high-pressure valve.
  • a high-pressure fuel pump comprising a pump housing; a fuel delivery duct; and a fuel delivery valve, which extends along a longitudinal axis, is arranged along the delivery duct, and comprises a valve seat directly machined in the pump housing; a shutter movable between a closed and an open position in the valve seat; a fastening member suitable for being fastened to the pump housing; a helical spring suitable for biasing the shutter in the closed position; and a sleeve, which is fitted to the fastening member and comprises a sealing ring, which defines a fuel passage and an abutment for said shutter so as to allow the shutter closing the fuel passage;
  • the high-pressure fuel pump being characterised in that the sealing ring is coupled to the valve seat in fluidthight manner and the fastening member comprises a bolt threaded into the valve seat; a first protrusion force fitted into the sleeve and a second protrusion force fitted into the helical spring.
  • the shutter does not come into contact with the valve seat so that the pump housing is prevented from being worn out and/or damaged by the shutter.
  • the fastening member, the shutter, the helical spring, and the sleeve can be assembled together to form a valve assembly, before inserting the valve assembly in to the valve seat and positioning correctly the sealing ring .
  • the assembling steps of the high-pressure fuel pump are simplified.
  • reference numeral 1 indicates as a whole a high-pressure fuel pump suitable for receiving fuel from a low pressure pump (not shown) and for compressing the fuel to pressures higher than 2200 bars for feeding the fuel itself to a common rail of an internal combustion diesel-engine (not shown) in the enclosed figure.
  • Pump 1 comprises a pump housing 2 essentially made of a block of metallic material, in which there are machined a cylinder (not shown), a fuel feeding duct (not shown) to the cylinder, a fuel delivery duct 3; and a delivery valve 4 arranged along the delivery duct 3.
  • the delivery duct 3 is directly machined in the pump housing 2 and comprises a hole 5 upstream of the valve 4; and a hole 6 downstream of the valve 4.
  • the valve 4 comprises a seat 7 directly machined in the pump housing 2 between hole 5 and hole 6.
  • Hole 5 and seat 7 extend in sequence about a longitudinal axis A, while hole 6 extends radially with respect to the longitudinal axis A and departs from seat 7.
  • Seat 7 is delimited by a hole 8 larger than hole 5 and coaxial with hole 5; a truncated cone-shaped face 9 converging towards hole 5; a curved surface 10 flowing into a shoulder 11 perpendicular to the longitudinal axis A, and a further truncated cone-shaped face 12 bridging the shoulder 11 to hole 5 and converging towards hole 5.
  • the seat 7 can be accessed from the outside of the pump housing 2 through a further hole 13, which is larger than hole 8 and is adjacent to an outer face of the pump housing 2.
  • Hole 13 is provided with an inner thread and is closed by a threaded bolt 15 in fluid-tight manner.
  • Bolt 15 comprises a portion suitable to abut against shoulder 14 and securing tightness.
  • the valve 4 comprises in addition to seat 7, a fastening member 16; a shutter 17; a helical spring 18 compressed between the fastening member 16 and shutter 17; and sleeve 19, which is fitted to the fastening member 16 and houses the shutter 17 and the helical spring 18.
  • Fastening member 16, shutter 17, helical spring 18, and sleeve 19 are housed in the seat 7 and are arranged along longitudinal axis A.
  • the fastening member 16 comprises a bolt 20, which is provided with an outer thread for engaging a threaded portion of hole 8; a protrusion 21 extending along longitudinal axis A from bolt 20; and a further protrusion 22, which extends along longitudinal axis A from protrusion 21.
  • Helical spring 18 is force fitted about protrusion 22, whereas sleeve 19 is force fitted about protrusion 21.
  • Fastening member 16 is provided with a through hole 23 extending along longitudinal axis A and aligned with longitudinal axis A.
  • shutter 17 is spear-shaped and is provided with a cone-shaped sealing member 24 flowing into a cylindrical portion 25 and a shank 26, which is force fitted in the helical spring 18.
  • the shank 26 is further provided with a blind hole 27 protruding inside the sealing member 25 to reduce the inertial mass of the shutter 17.
  • the shutter is ball-shaped.
  • Helical spring 18 comprises a number of turns 28 having a constant diameter and distributed with a constant pitch along longitudinal axis A.
  • Sleeve 19 comprises a cylindrical wall 29 arranged about longitudinal axis A and a sealing ring 30 defining a free edge of the cylindrical wall 29 (of the sleeve 19).
  • the cylindrical wall 29 is force fitted about the protrusion 21 of the fastening member 16 and the sealing ring 30 is located on the side opposite to the fastening member 16.
  • the sealing ring 30 is coupled to the valve seat 7 in fluid-tight manner.
  • the sealing ring 30 is forced against shoulder 11 by threadeadly engaging bolt 20 into hole 8.
  • Sealing ring 30 is provided with an outer sealing surface 31 matching with the curved surface 10 of the valve seat 7 and an inner sealing surface 32 matching with the shape of sealing member 24 of the shutter 17 when the shutter 17 is in the closed position.
  • Cylindrical wall 29 is spaced apart from hole 8 (the outer diameter of the wall 29 is smaller than the diameter of hole 8) so that an annular chamber is formed between the cylindrical wall 29 and the seat 7.
  • the cylindrical wall 29 is provided with a number of openings 33 in close proximity to sealing ring 30 so that displacement of the shutter 17 let the fuel flowing from a central passage of the sealing ring 30 to the openings 33 into the annular chamber and, then, into hole 6.
  • the cylindrical wall 29 is further provided with a number of further openings 34 arranged circumferentially in the middle of the cylindrical wall 29 so as to avoid that fuel dwelling inside the sleeve 19 disturbs the displacement of the shutter 17.
  • the inner diameter of the sleeve 19 and the outer diameter of the cylindrical portion 25 of the shutter 17 are selected so that the sleeve 19 guides the displacement of the shutter 17 along longitudinal axis A and avoids lateral displacement of the shutter 17 and any misalignment of the shutter 17 with respect to longitudinal axis A.
  • the shutter 17 and the sleeve 19 are slindingly coupled along longitudinal axis A.
  • shutter 17 does not come into contact with the valve seat 7 so that the pump housing 2 is prevented from being worn out and/or damaged by the shutter 17; the fastening member 16, the shutter 17, the helical spring 18 and the sleeve 19 can be assembled so as to form the valve assembly 35 before inserting it into the valve seat 7 so simplifying the assembling steps; and, should some part of the valve assembly 35 be worn out or damaged during use, the valve assembly 35 can be easily and conveniently be replaced by a new assembly 35 without calling for the replacement of the high-pressure fuel pump 1.
