Control mechanism described in the utility model 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.

Texturing zone in the utility model can be the elastic deformation area, inelastic deformation district or slip texturing zone.Elastic region in the utility model 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.

In the structure of external-open valve head of the present utility model, 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 described in the utility model can be made as arc.

The fluid source of indication can be made as or not be made as high-pressure fluid source in the utility model, 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.Its objective is to provide fluid with the inner chamber of direct-control direct-injection type shell deformation fluid injector to motor disclosed in the utility model.

The effect of one-way valve is to prevent that the fluid that imports inner chamber from coming back in the fluid source in the utility model, to guarantee the pressure of fluid in the inner chamber, realization does not have the fluid jet under the situation of high-pressure fluid source, so just can not have the high-pressure installation of conventional fluid supply system, and is simple in structure.

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.Motor described in the utility model is not have the conventional high-tension fluid supply apparatus with the key technology of direct-control direct-injection type shell deformation fluid injector, under the effect of control mechanism, produce deformation by the deformation district on the fluid ejector housing, realize the relative displacement of external-open valve head and external-open valve opening, finish the injection of fluid.

The valve tail in the utility model 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.

Motor described in the utility model is to adjust the cracking pressure and the closing pressure of valve head and valve opening by the thickness of adjusting pad with the purpose of adjusting pad is set in the direct-control direct-injection type shell deformation fluid injector.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.

It is in order to occupy the volume of inner chamber, to prevent that the amount of fuel in the locking system is excessive, produce excessive compression volume under the high pressure effect, reducing thereby cause spraying response that hard described in the utility model accounts for the purpose of holding body.Described hard accounts for the shape of holding body and does not limit, and material can be a steel, pottery etc.

Rigidization formula fluid ingress pipe in the utility model is meant the deformation quantity for fluid ingress pipe under the effect that reduces the high voltage pulse fluid, and the convection cell ingress pipe carries out the fluid ingress pipe of prestressing force processing, for example the fluid ingress pipe being carried out ultrahigh pressure suppresses, allow the suffered power of fluid ingress pipe reach YIELD STRENGTH, thereby reduce the deformation quantity of fluid ingress pipe when the high-pressure liquid pressure release.

The external-open valve head in the utility model and the fitting surface of external-open valve opening can be multiple combinations, the surface fuel injection hole can replace fuel injection hole, and surperficial fuel injection hole is on external-open valve head surface or the surface delineation of external-open valve opening processes, thus can process more tiny.

The adjustment of injection pressure can be by the ratio of sectional area or recently the realizing of the sectional area between elastic region and the spray-hole of adjusting elastic region and valve opening, also can realize by shape and the combined shaped thereof that changes the face that valve head and valve opening match.For example when the combination of cylinder and the conical surface, when the deformation of elastic region during less than cylinder length, fuel oil can not spray, and has only when the deformation of the elastic region length greater than cylinder, could form injection, so the fuel-injected initial pressure has obtained raising greatly.

Because motor disclosed in the utility model can be done very for a short time with the external diameter of direct-control direct-injection type shell deformation fluid injector, so can arrange a plurality of in a firing chamber.

The utility model has following useful effect: volume is little, heat resistance is good, it is fast to spray response, there is not traditional fuel oil high voltage supply device, 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.
