Described control mechanism is made as cammingly control mechanism, electromagnetic type control mechanism or hydraulic type control mechanism, between described control mechanism and described seal casinghousing, adjust pad if do not establish the gap, between described control mechanism and described seal casinghousing if do not establish elastomer.
Control mechanism of the present invention can be cam, electromagnetic mechanism, hydraulic mechanism or other requirements that can concern according to the amount and the timing of motor opposing jet body, make valve tail and enclosing housing joint be subjected to displacement the mechanism that causes the valve head displacement that valve opening is closed and opened.
Be made as in the structure of swing-in valve head at valve head, when needing to spray, control mechanism will apply the external force away from the valve opening direction to valve tail and enclosing housing joint, because the existence of elastic region on the enclosing housing, this external force can make the valve head displacement cause valve opening to open formation fluid jet.When needing to stop spraying, then cancel this external force and get final product.In order to keep the high-seal of valve opening and valve head, can be by adjusting assembly relation, promptly adjust the assembly relation of seal casinghousing and valve body, make the elastic region when not needing to spray, have certain pre-stretching deformation, thereby form the pressure maintenance sealing of valve head valve opening.
Be made as in the structure of swing-in valve head at valve head, also can be by adjusting the position assembly relation between control mechanism and the described directly controlled shell body deformation fluid ejector for engine, be formed on when not spraying, control mechanism is exerted pressure to the elastic region, make the elastic region when not spraying, have precompression deformation, cause that valve head has certain pressure to valve opening when not spraying, keep sealing.When needs sprayed, control mechanism reduced or cancels the effect to the compressing area, and compressing area drive valve head generation displacement is opened valve opening to form and sprayed.
Be made as in the structure of outward opening valve head at valve head, when need spraying, control mechanism will apply the external force of a convergence valve opening direction to valve tail and enclosing housing joint, owing to the existence of elastic region on the enclosing housing, this external force can make the valve head displacement open valve opening, forms fluid jet.When needing to stop spraying, then cancel this external force and get final product.In order to keep the high-seal of valve opening and valve head, also can allow the elastic region when not needing to spray, have certain precompression deformation by adjusting assembly relation.
Enclosing housing inner valve stem of the present invention can be made as arc.
The high-pressure fluid source of indication can be the supply source of source of high pressure, High Temperature High Pressure air source (gas holder), high-temperature high-pressure steam source (high-temperature high-pressure steam generator or high-temperature high-pressure steam storage tank) or other fluids that need spray among the present invention.Its objective is to provide the fluid with certain pressure to the inner chamber of directly controlled shell body deformation fluid ejector for engine disclosed in this invention.
Traditional fuel injector is that the deformation by built-in spring causes valve body to produce displacement, thereby finishes the open close of oil circuit.Based on this structure, just must have movable plunger coupled parts in the fluid ejector, because the existence of plunger coupled parts, the leakage of fuel oil is just inevitable, therefore must be provided with oil return system in traditional fuel injector, it is complicated that the structure of fuel injector just becomes.The machining accuracy of plunger coupled parts and cost are higher in addition, and heat resistance is relatively poor.The key technology of directly controlled shell body deformation fluid ejector for engine of the present invention is to produce deformation by the elastic region on the fluid ejector housing under the effect of control mechanism, realizes the relative displacement of valve head and valve opening, finishes the injection of fluid.
The valve tail among the present invention and the Connecting format of enclosing housing are various, can be fixed connections, and the clamp groove-fastening type connects, and the nut-screw formula connects, and can be that elasticity connects, and also can be to be tightly connected.
Elastic region among the present invention can be multiple shape, also can constitute by the elastomer of not planting shape, can be that integral body processes, after also can processing separately by elastic material, with the two ends of elastic region and the housing formation sealed cavity that connects firmly or be tightly connected, also the sidewall of whole enclosing housing can be made as the elastic region, that for example enclosing housing can be done is more elongated, under the effect of control mechanism, the purpose that deformation reaches fluid jet takes place in enclosing housing in the longitudinal direction.
It is cracking pressure and the closing pressure of adjusting valve head and valve opening by the thickness of adjusting pad that the purpose of adjusting pad is set in the directly controlled shell body deformation fluid ejector for engine of the present invention.The setting of guide structure body is in order valve body to be play the guiding role, to avoid valve head contacts decentraction with valve opening phenomenon, strengthening the location accuracy of valve body.In addition, gland nut, in receive and the setting of circumsphere also has the effect of strengthening the valve body location accuracy.
The setting of fluid export interface is to derive for the fluid that will enter enclosing housing.For example, overheated for preventing valve head and valve opening, segment fluid flow can be derived to reach the purpose of heat radiation, avoid because of the temperatures involved valve head of engine chamber and the fitted seal of valve opening.The place can establish control valve at the fluid export interface, and the fluid of being derived can be got back in the high-pressure fluid source through pressurization, in some cases, and also can emptying.
Flow guide structure is the structure that is provided with in order to make the qualitative motion of the fluid that sprays in the cylinder, can be that pipeline or other can make the structure of fluid orientation movement.Its objective is in order to increase the motion of cylinder inner fluid, reach the purpose that oil gas mixes and sprayed into fluid mixes with gas in the jar.
The purpose of pre-sealed insulator setting is in order to reduce the temperature of elastic region.But non-tight is slidingly connected and is meant both slide relative of two surface of contact, can have fluid to pass through between two surface of contact again.Because non-tight is slidingly connected and/or the setting of pressure compensation opening, the pressure of pre-sealed insulator and elasticity insulator both sides can be in a basic balance.Pre-sealed insulator and/or elasticity insulator can stop with the elastic region fluid in contact and upgrade fast, reach the effect of elastic region, sealing elastic region and the cooling of end sealing elastomer.
Because the external diameter of directly controlled shell body deformation fluid ejector for engine disclosed in this invention can be done very for a short time, so can arrange a plurality of in a firing chamber.
The present invention has following useful effect: volume is little, and heat resistance is good, sprays response soon, and the fluid jet amount is more accurate, and the injection response is faster, not only can be used for fuel injection, also can be used for other fluid jets, for example the injection of the injection of High Temperature High Pressure air or high-temperature high-pressure steam.
