Abstract
The present invention features that a rotary and axially displaceable oil-separating, throttling and check valve plug for fuel distribution in IC engine is installed in a valve sleeve. Under the combined action of other devices, intermittent and variable throttle holes are formed between the end faces of the oil inlet and outlet holes on the valve sleeve and the plug. The valve is of an inlet throttling type structure. Therefore, the valve can be suitable for fuel distribution of internal combustion engines with different displacement, cylinder number, fuel types, fuel supply modes and any structures requiring ultrahigh pressure injection.
Description
The present invention relates to a kind of pulsating inlet throttling type internal combustion engine fuel distributing valve.
The fuel pulsation supply system of existing internal-combustion engine generally uses special plunger pump or direct action solenoid valve to computerized control and is achieved.Because the structure of these certain device and its performance are limit, make its pulsation system manufacture cost, debug all difficulty and the narrow limitation of various degrees such as maintenance in complexity, adaptive capacity and the using process, maintenance.
The purpose of this invention is to provide a kind of pulsating inlet throttling type internal combustion engine fuel distributing valve.The jerk type internal-combustion engine ultrahigh pressure fuel distributing valve that the adjusting of this valve collection fuel distribution, delivery volume and control, non-return and the repeatedly fuel distributing function in different amount are done one.The internal-combustion engine ultrahigh pressure fuel supply system that this valve can be applicable to different displacements, cylinder number, fuel type, governor control characteristics and requires multistage fuel distributing in the work cycle.
The present invention is characterized in that having a cylinder type endoporus in the valve pocket, and has 1～24 radially oil inlet hole on the same section between its diaxon end face, and at the radially oil outlet that equally also has equivalent amount on the aforementioned section on another section; Being equipped with one in the valve pocket not only can be around himself rotational but also can be at the moving cylindrical column type valve plug of string on himself axial direction; It is characterized in that having in the valve plug 1～3 oil input channel, constituted intermittence, variable orifice between the exterior edge face of its oil input channel and the interior edge face of the oil inlet hole on the valve pocket; And the input end of the oil road in the output terminal of its oil input channel and the valve plug is communicated with; When valve plug simultaneously around himself rotational and moving during to certain position along himself axis string, constituted between the exterior edge face of the oil input channel in the valve plug and the interior edge face of the oil inlet hole on the valve pocket intermittently, the output terminal of the oil road variable orifice the time in the valve plug also with valve pocket on the oil outlet connection.
Advantage of the present invention: 1, be applied in the fuel pulsation formula of internal-combustion engine or multistage during dispensing when this valve, this valve has its unique governor control characteristics again; 2, because of this valve belongs to the two-freedom control type, so the control of fuel distributing amount, regulation range are very wide; 3, simple in structure, cost is low, volume is little, in light weight, can be adapted to be installed on any position of internal-combustion engine; 4, because of this valve belongs to the rotation dispensing, rotary inertia is little, so can satisfy very high dispensing frequency; 5, can satisfy the fuel distributing of the inside and outside fuel injection system of cylinder of internal-combustion engine; 6, because of this valve belongs to the inlet throttle formula, so its voltage endurance capability can reach very high value, for the ultrahigh pressure fuel injection system provides a kind of brand-new allocation device.
Further specify the present invention below by example and accompanying drawing.
Accompanying drawing 1 is a structural representation of the present invention.
Accompanying drawing 2 is an A-A sectional drawing of the present invention.
Accompanying drawing 3 is a B of the present invention district enlarged view.
The present invention has a cylinder type endoporus (5) in the valve pocket (1), and has 1～24 radially oil inlet hole (7) on the same section between its diaxon end face, and is equally also having the radially oil outlet (3) of equivalent amount on the aforementioned section on another section; Being equipped with one in the valve pocket (1) not only can be around himself rotational but also can be at the moving cylindrical column type valve plug (2) of string on himself axial direction; It is characterized in that 1～3 oil input channel (8) is arranged in the valve plug (2), constituted intermittence, variable orifice between the exterior edge face (9) of its oil input channel (8) and the interior edge face (10) of the oil inlet hole (7) on the valve pocket (1); And the input end of the oil road (6) in the output terminal of its oil input channel (8) and the valve plug (2) is communicated with; When valve plug (2) simultaneously around himself rotational and moving during to certain position along himself axis string, constituted intermittently between the exterior edge face (9) of the oil input channel (8) in the valve plug (2) and the interior edge face (10) of the oil inlet hole (7) on the valve pocket (1), the output terminal (4) of the oil road (6) in the valve plug in the time of variable orifice (2) also with valve pocket (1) on oil outlet (3) connection.
External liquid or gaseous fuel with certain pressure enter through input hole (7); So simultaneously valve plug (2) is moving to certain position along himself axis string again in himself rotational under the effect of other device, at this moment constituted intermittence, variable orifice between the interior edge face (10) of the exterior edge face (9) of the oil input channel (8) in the valve plug (2) and the oil inlet hole (7) on the valve pocket; When this throttle orifice forms, the pressure fuel that has been accumulated in this will flow out valve pocket through the oil outlet (3) on the oil input channel (8) in this throttle orifice enters valve plug (2), oil road (6) and the valve pocket; And when valve plug (2) continues rotation, valve plug (2) but the outer cylinder above-mentioned oil inlet hole (7) and the oil outlet (3) that put of cut-off valve again, at this moment constituted again between the outer cylinder of valve plug (2) and valve pocket endoporus (5) cylinder and prevented that pressure fuel from entering and backflow functionality once more; Change the axial displacement of valve plug (2), the orifice size of intermittence, the variable orifice of its formation is changed or fixedly valve plug (2) axial position and when changing the rotating speed of valve plug (2), the time that constitutes throttle orifice equally also can obtain changing, and how much the fuel quantity by throttle orifice can change with the change of the change in rotational speed amount of the axial displacement of valve plug (2) or its valve plug (2) in sum.
