Description
Technical field:
The utility model relates to a kind of high-speed switch valve that is used for the Control of Automobile automatic transmission clutch.
Background technique:
The high-speed switch valve of prior art, because its seal form is conical surface seal, the stroke of valve thimble when opening or closing is longer, then the restoring force of spring is bigger, thimble and poppet valve core impact force when replying is just big, therefore thimble and poppet valve core is easy to wear, fatiguability, working life are short, noise is big during opening and closing, speed of response is slow.
The model utility content:
The utility model at above problem provide a kind of when opening or closing the stroke of thimble short, the high-speed switch valve that thimble and steel ball spool are not easy to wear, noise is little, speed of response is fast when indefatigability, long service life and opening and closing.
The utility model overcomes the above problems used technological scheme: a kind of high-speed switch valve with following structure is provided, it comprises electromagnet assembly, valve body, thimble, spring I and spring II, described electromagnet assembly is connected with valve body, be provided with armature in the center hole of described valve body from top to bottom successively, guide holder, valve seat and plug, described valve seat is separated into oil pocket I and oil pocket II with the center hole between guide holder and the plug, oil pocket I sidewall and oil pocket II sidewall are respectively equipped with return opening C and filler opening A, sidewall is provided with oil outlet B between return opening C and the filler opening A, described valve seat is provided with the through hole that is communicated with center hole and oil outlet B, described thimble one end is connected with armature, the other end sliding fit is in the center hole of guide holder, and extend in the valve base center hole, be provided with the steel ball spool that the mating face with valve base center hole and lower end surface matches among the described oil pocket II, spring I one end pushes against plug, and the other end pushes against the steel ball spool.
After adopting above structure, the utility model compared with prior art, owing to adopted the mating face of steel ball spool and valve base center hole and lower end surface to match to come sealing channel, therefore unlatching of the present utility model or when closing the stroke of thimble shorter, so thimble and steel ball spool are not easy to wear, noise is little when indefatigability, long service life and opening and closing, speed of response is fast.
As further improvement, be provided with filter screen among the described oil pocket II, therefore improved the reliability height and the long service life of antifouling property of the present utility model, use.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure: 1, shell, 2, coil, 3, plastic packaging, 4, armature, 5, valve body, 6, guide holder, 7, thimble, 8, valve seat, 9, the steel ball spool, 10, spring I, 11, filter screen, 12, plug, 13, spring II, 14, skeleton, 15, the bellows seal circle, 16, pin, 17, oil pocket I, 18, the O RunddichtringO, 19, oil pocket II.
Embodiment:
Below in conjunction with accompanying drawing and concrete embodiment, the utility model is described further, but the utility model is not limited to following concrete embodiment:
A kind of as shown in drawings high-speed switch valve, it comprises electromagnet assembly, valve body 5, thimble 7, spring I 10 and spring II 13, described electromagnet assembly is connected with valve body 5, described electromagnet assembly comprises shell 1, coil 2, plastic packaging 3 and skeleton 14, coil 2 is spacing in shell 1 by plastic packaging 3 and skeleton 14, the outer wall of shell 1 is provided with pin 16, pin 16 is connected with PWM (pulsewidth width modulated formula) the electrohydraulic digital control system of prior art, the axis of shell 1 center hole and the center hole axis of valve body 5 are on same straight line, be provided with armature 4 in the center hole of described valve body 5 from top to bottom successively, guide holder 6, valve seat 8 and plug 12, described spring II 13 1 ends prop up the step end face of shell 1 center hole, the other end props up armature 4, described valve seat 8 is separated into oil pocket I 17 and oil pocket II 19 with the center hole between guide holder 6 and the plug 12, oil pocket I 17 sidewalls and oil pocket II 19 sidewalls are respectively equipped with return opening C and filler opening A, sidewall is provided with oil outlet B between return opening C and the filler opening A, described valve seat 8 is provided with the through hole that is communicated with center hole and oil outlet B, between the outer surface return opening C of valve body 5 and oil outlet B and oil outlet B and filler opening A, be equipped with O RunddichtringO 18, described thimble 7 one ends are connected with armature 4, the other end sliding fit is in the center hole of guide holder 6, and extend in valve seat 8 center holes, be provided with the steel ball spool 9 that the mating face with valve seat 8 center holes and end face matches among the described oil pocket II 13, spring I 10 1 ends push against plug 12, and the other end pushes against steel ball spool 9.
