Description
[001] Izgudrojums attiecas uz iekšdedzes motoru barošanas sistēmām ar regulējamu gaisa (gāzu) vai degmaisījuma padeves mehānismu.The present invention relates to internal combustion engine power systems with an adjustable air (gas) or combustion mixture delivery mechanism.
Zināmais tehnikas līmenis [002] Ir zināmi droseļvārsti [1, 2, 3], kas izmanto plūsmas kanālu, kura šķērsgriezuma laukuma izmainīšana notiek ar rotējošu slēdzējelementu palīdzību. To trūkums ir tas, ka pilnībā atvērtā droseļvārsta stāvoklī slēdzējelementu novietojums palielina plūsmas pretestību. Centrētas plūsmas droseļvārstā [1] slēdzējelementi atrodas plūsmas kanāla perifērijā un ar savu formu palielina plūsmas pretestību. Droseļvārstā ar nobīdītas rotācijas ass slēdzējelementu [2] plūsmas pretestību pilnībā atvērtā droseļvārsta stāvoklī palielina dobums, kas izveidojas plūsmas kanālā. Plastmasas droseļvārstā [3] plūsmas pretestību pilnībā atvērtā stāvoklī palielina izgriezums, kas veidojas, slēdzējelementam atrodoties pilnībā atvērtā stāvoklī.BACKGROUND OF THE INVENTION Throttle valves [1, 2, 3] are known which use a flow channel whose cross-sectional area is changed by rotating locking elements. Their disadvantage is that the position of the locking elements increases the flow resistance when the throttle is fully open. In a centrifugal flow butterfly valve [1], the shut-off elements are located at the periphery of the flow channel and increase their flow resistance by their shape. The flow resistance of a throttle valve with an offset rotary shaft shutter element [2] in the fully open throttle position is increased by the cavity formed in the flow channel. In the plastic butterfly valve [3], the flow resistance in the fully open position is increased by a cut formed when the locking element is in the fully open position.
Izgudrojuma mērķis un būtība [003] Piedāvātā izgudrojuma mērķis ir panākt plūsmas kanālā centrētu plūsmu daļēji atvērtā droseļvārsta stāvoklī un izslēgt slēdzējelementu ietekmi uz plūsmas pretestību pilnībā atvērtā droseļvārsta stāvoklī.OBJECTIVE AND SUMMARY OF THE INVENTION The object of the present invention is to achieve a flow channel centered flow in the partially open throttle position and to exclude the effect of the locking elements on the flow resistance in the fully open throttle position.
[004] To panāk ar to, ka slēdzējelementos izveidotās noslēgta kontūra atveres iekšējā virsma sakrīt ar plūsmas kanāla korpusa iekšējo virsmu pilnībā atvērtā droseļvārsta stāvoklī. Konkrētā izpildījumā cilindriskas formas, koncentrisku slēdzējelementu kinemātiskā saistība ar zobratu vai citu pārvadu nodrošina tiem pretēju rotācijas virzienu. Pateicoties tam, slēdzējelementi veido plūsmas kanāla šķērsgriezuma sašaurinājumu, kura laukuma centrs sakrīt ar plūsmas kanāla šķērsgriezuma laukuma centru daļēji atvērtā droseļvārsta stāvoklī. Slēdzējelementu pagriešanu nodrošina tiem piestiprināti iekšējās sazobes zobratu sektori ar zobratu pāra starpniecību.This is achieved by the fact that the inner surface of the closed loop opening formed in the locking elements coincides with the inner surface of the flow channel housing in the fully open throttle position. In a particular embodiment, the kinematic relationship of the cylindrical, concentric locking members to the gear or other gear provides them in the opposite direction of rotation. Due to this, the locking elements form a narrowing of the cross-section of the flow channel whose center of the area coincides with the center of the cross-section of the flow channel in the partially open throttle position. Rotation of the locking elements is ensured by the sectors of the internal gear teeth fixed to them by means of a pair of gears.

Izgudrojuma īstenošanas piemērs [008] Droseļvārsta korpuss (1) satur (skat. 1. un 3. zīm.) plūsmas kanālu (2) un pievienotus cilindriskas formas, koncentriskus slēdzējelementus (3, 4), kuru centra ass (5) perpendikulāra plūsmas kanāla (2) centra līnijai (6). Slēdzējelementiem (3, 4) ir piestiprināti iekšējās sazobes zobratu sektori (7, 8), ar kuriem sazobē atrodas zobratu pāris (9). Pie viena no zobratu pāra (9) zobratiem ir pievienota piedziņas vārpsta (10).Example of Embodiment of the Invention The throttle body (1) comprises (see Figures 1 and 3) a flow channel (2) and attached cylindrical concentric locking elements (3, 4) having a center axis (5) perpendicular to the flow channel (2) the center line (6). The locking elements (3, 4) are provided with sectors (7, 8) of internal gears with which a pair of gears (9) are located in the gear. A drive shaft (10) is attached to one of the gears of a pair of gears (9).
[009] Droseļvārsta darbība ir sekojoša. Plūsmas kanāla (2) atvērums (skat. 1., 2. un 3. zīm.) tiek izmainīts ar rotējošu slēdzējelementu (3, 4) palīdzību, kuri regulē iekšdedzes motorā ieplūstošā gaisa (gāzu) vai degmaisījuma daudzumu. Pagriežot piedziņas vārpstu (10), ar zobratu pāra (9) un iekšējās sazobes zobratu sektoru (7, 8) starpniecību, notiek slēdzējelementu (3, 4) rotācija un tajos izveidotās noslēgta kontūra atveres, savstarpēji pārklājoties, izmaina plūsmas kanāla (2) efektīvo šķērsgriezuma laukumu (11), koncentrējot gaisa (gāzu) vai degmaisījuma plūsmu kanāla (2) centrā. Pilnībā atvērtā stāvoklī, slēdzējelementos (3, 4) izveidoto noslēgta kontūra atveru iekšējā virsma (12, 13) sakrīt ar plūsmas kanāla (2) korpusa (1) iekšējo virsmu (14).[009] The throttle valve operates as follows. The opening of the flow passage (2) (see Figures 1, 2 and 3) is changed by means of rotary locking elements (3, 4) which regulate the amount of air (gas) or combustion mixture entering the combustion engine. By rotating the drive shaft (10), through the pair of gears (9) and the gearing sectors (7, 8), the locking elements (3, 4) are rotated and the closed loop openings formed therein mutually alter the effective flow of the flow channel (2). a cross-sectional area (11) concentrating the flow of air (gas) or combustion mixture in the center of the channel (2). In the fully open position, the inner surface (12, 13) of the closed loop openings formed in the locking elements (3, 4) coincides with the inner surface (14) of the housing (1) of the flow channel (2).
[010] Piedāvātais iekšdedzes motora droseļvārsts ir ieteicams izmantošanai sacīkšu motoru barošanas sistēmās.The proposed internal combustion engine throttle valve is recommended for use in racing engine power systems.
