5.2 deviate from the side end face of putter body 5.1 1, and described groove 5.3 formd oily passage.
Described groove 5.3 is four, and four grooves 5.3 are provided at circumferentially spaced along putter body 5.1, four grooves
5.3 are circumferentially uniformly arranged so that the cross section of putter body 5.1 is " cross " type.
The end face of the nearly putter body 5.1 of described cylinder 5.2 is provided with boss 5.4, and described boss 5.4 is located at cylinder
Between the outer wall of body 5.2 and the outer wall of putter body 5.1, the boss 5.4 is integrally formed with cylinder 5.2, as shown in Fig. 2 this reality
The boss 5.4 for applying example is also classified into four parts, forms the boss 5.4 of one big " cross ", and the position of boss 5.4 and putter body
5.1 cross chimb position is in same straight line, and this structure is convenient to be produced, and manufacturing cost is low, saves raw material, it is easy to volume production.
As shown in FIG. 1 to 3, a kind of magnetic valve that the utility model is provided, it includes shell 1, inner cover 2, coil 8 and work
Make portion, described work department includes valve rod 9, valve pocket 10, spring 11 and spring base 12, and described inner cover 2 is externally provided with pole shoe 3,
Nearly openend is provided with lower pole shoe 4 in the inner cover 2, and described lower pole shoe 4 surrounds to form chamber 6 with the inwall of inner cover 2, the chamber
Being provided with 6 can be along the reciprocating armature 7 of the central axis direction of inner cover 2, and described magnetic valve also includes push rod 5, described
Armature 7 is axially arranged with the first centre bore 7.1, and described lower pole shoe 4 is axially arranged with the second centre bore 4.1, the closely lower pole of the armature 7
The end face of boots 4 is recessed mounting groove 7.2 along the first centre bore 4.1, and the cylinder 5.2 of the push rod 5 is arranged on mounting groove 7.2
Interior, end face of the cylinder 5.2 away from putter body 5.1 and the distance between end face of the boss 5.4 away from cylinder 5.2 are big
In the groove depth of mounting groove 7.2, in other words i.e., armature 7 moves under the active force in magnetic field and drives the down direction of pole shoe 4 of push rod 5
When being moved to extreme position, the end face of boss 5.4 and the lower end face of pole shoe 4 between the end face of armature 7 and the lower end face of pole shoe 4 against and staying
There is gap, will not fit, the putter body 5.1 of the push rod 5 is arranged in the second centre bore 4.1, described push rod sheet
The end face of the closely lower pole shoe 4 of body 5.1 is resisted against the end face of the valve rod 9 of magnetic valve, and spring is provided between described valve rod 9 and valve seat 12
11, valve rod 9 is withstood in described one end of spring 11, and the other end withstands spring base 12；
During work, coil 8 is powered, and magnetic field force is formed in inner cover 2, and armature 7 drives push rod 5 to transport under the action of a magnetic force
Dynamic, push rod 5 promotes valve rod 9 to move, and the oil inlet on valve pocket 10 is connected with the oil-through-hole on valve rod 9, fluid passes through groove
5.3 enter the first centre bore 7.1 so that the pressure balance of the two ends chamber of armature 7 so that the motion of push rod 5 is not hindered by oil pressure
Power is influenceed and gently moved, and when being stopped, coil 8 is powered off, and magnetic field force disappears, the not magnetic field force induced effect of armature 7,5 pairs of push rod
The thrust of valve rod 9 disappears, and valve rod 9 then resets to home position under spring force, i.e. armature 7 is in electromagnetic force and spring force
Under collective effect, in the cathetus reciprocating action of inner cover 2, so as to drive push rod 5 and valve rod 9 to act, realize magnetic valve commutation and
Throttling function.
The described external diameter of boss 5.4 is more than the aperture of the second centre bore 4.1, so down the direction of pole shoe 4 is moved when push rod 5
When, boss 5.4 serves barrier effect, it is to avoid the end face of armature 7 fits with the lower end face of pole shoe 4.
