Abstract
The utility model discloses a floating valve for an engine, which comprises a passageway and a seat opening, wherein the seat opening is arranged in the passageway; a floating valve body is arranged at the seat opening and is connected with a control structure in a floating manner; the control structure is controlled by a control mechanism; and one end of the passageway is communicated with a cylinder of the engine, and the other end of the passageway is communicated with a working medium cavity. By adopting the floating valve for the engine, which is disclosed by the utility model, the gas distribution efficiency of the engine can be effectively improved.
Description
Technical field
The utility model relates to engine art, especially a kind of floating valve.
Background technique
Distributing valve on the motor all receives control mechanism control in correct time by concerning accurate correct time; Yet import cylinder or in the technological scheme that cylinder is derived, traditional timing mechanism control can't reach requirement at need be according to the gas pressure in the engine cylinder big young pathbreaker's gas working medium.Therefore, need a kind of novel distributing valve of invention.
Summary of the invention
In order to address the above problem, the technological scheme that the utility model proposes is following:
A kind of motor is used floating valve; Comprise a passage and a mouth, said seat mouth is located in the said passage, locates to establish unsteady valve body at said seat mouth; Said unsteady valve body floats with the control structure body and is connected; The controlled mechanism controls of said control structure body, an end of said passage is communicated with the cylinder of motor, and the other end of said passage is communicated with working fluid chamber.
The unsteady joint of said unsteady valve body and said control structure body is arranged in the said unsteady valve body.
Said unsteady valve body and unsteady valve body connecting rod are connected, and said control structure body floats with said unsteady valve body through said unsteady valve body connecting rod and is connected.
Said control mechanism is made as cammingly control mechanism, hydraulic type control mechanism or electromagnetic type control mechanism.
In the utility model; So-called unsteady connection is meant that the stroke at said control structure body is in the certain limit; Said unsteady valve body is not controlled by said control structure body; Only receiving the pressure reduction control of said unsteady valve body both sides freely to open or close (check valve that is equivalent to free state) makes said passage open or close; And when the stroke of said control structure body during greater than certain limit, regardless of the pressure reduction situation of said unsteady valve body, said unsteady valve body receives said control structure body control to make said passage open or close.
In the utility model; Open under the effect of said unsteady valve body at gas in the jar when gas pressure acquires a certain degree in compression stroke when said cylinder gas in the jar is pressed in the said working fluid chamber through said passage; When piston begins when descending through top dead center; Said unsteady valve body still is in opening state under the effect of said control mechanism and said control structure body, descending along with piston, and the part of the working medium in the said working fluid chamber is back in the said cylinder; When the piston in the said cylinder left top dead center and acquires a certain degree, said unsteady valve body mouthful was closed said seat under the effect of said control mechanism and said control structure body; On said cylinder, be provided with in the structure of fuel inlet, under the effect of said control mechanism and said control structure body, keep closed condition at the valve body that floats described in the combustion process.
In the utility model,, necessary parts, unit or system are set in the place of necessity according to the known technology of engine art.
The beneficial effect of the utility model is following:
Motor disclosed in the utility model can be derived gas working medium according to the big young pathbreaker's gas working medium importing cylinder of motor gas pressure in the cylinder in each stroke or from cylinder with floating valve; And, can improve the distribution efficient of motor effectively where necessary through said control mechanism and its switching of said control structure body control.
Description of drawings
Shown in Figure 1 is the utility model embodiment 1 structural representation;
Shown in Figure 2 is the utility model embodiment 2 structural representation,
Among the figure:
1 passage, 2 valve bodies, 3 control structure bodies, 4 mouths, 5 control mechanisms, 6 cylinders, 7 working fluid chambers, the 8 valve body connecting rods that float that float.
Embodiment
Embodiment 1
Motor as shown in Figure 1 is used floating valve, comprises passage 1 and seat mouth 4, and said seat mouth 4 is located in the said passage 1; Mouthful 4 places establish the valve body 2 that floats at said seat; Said unsteady valve body 2 and control structure body 3 floats and is connected, and said control structure body 3 controlled mechanisms 5 control, and an end of said passage 1 is communicated with the cylinder 6 of motor; The other end of said passage 1 is communicated with working fluid chamber 7; Wherein, the unsteady joint of said unsteady valve body 2 and said control structure body 3 is arranged in the said unsteady valve body 2, and said control mechanism 5 is the cammingly control mechanism.
Optionally, said control mechanism 5 also can be made as hydraulic type control mechanism or electromagnetic type control mechanism.
During work; When said cylinder 6 is in the compression stroke, piston stroking upward compresses gas, when gas pressure acquires a certain degree; Said unsteady valve body 2 is opened under the effect of cylinder pressure; Gas in the jar is pressed in the said working fluid chamber 7 through said passage 1, and when piston begins when descending through top dead center, said unsteady valve body 2 still is in opening state under the effect of said control mechanism 5 and said control structure body 3; Descending along with piston; The part of the working medium in the said working fluid chamber 7 is back in the said cylinder 6, and when the piston said cylinder 6 in left top dead center and acquires a certain degree, said unsteady valve body 2 was closed said seat mouth 4 under the effect of said control mechanism 5 and said control structure body 3; When said cylinder 6 is in the combustion explosion stroke, under the effect of said control mechanism 5 and said control structure body 3, keep closed condition at the valve body 2 that floats described in the combustion process.
Embodiment 2
Motor as shown in Figure 2 is used floating valve, and itself and embodiment's 1 difference is: said unsteady valve body 2 is connected with unsteady valve body connecting rod 8, and said control structure body 3 is through said unsteady valve body connecting rod 8 and said unsteady 2 unsteady connections of valve body.
Obviously; The utility model is not limited to above embodiment, according to the known technology and the technological scheme disclosed in the utility model of related domain, can derive or association goes out many flexible programs; All these flexible programs also should be thought the protection domain of the utility model.
