Description

Constant is widely used in hydraulic power steering.

The flow source is open tangential slide valve and axial rotary valve.

They usually.

It has the following characteristics:

(1) steering control valves are equipped with an output flow.

A steering hydraulic pump that is approximately a fixed value.

When the spool is in the middle.

The oil flows back to the fuel tank through the opening (pre-opening) of the valve.

The experimental results show that the symmetrical multilateral control valve can make the system have.

High force gain and speed gain, so steering control valve.

Most of them are 4 controllable throttle edges or channels.

(2) in order to make the driver's steering intention accurate and rapid.

The hydraulic signal necessary for ground conversion to power steering, inverted core.

It is usually directly controlled by the steering shaft or ball nut, and its displacement.

It has a simple proportional relationship with the steering wheel angle.

(3) all steering control valves are equipped with flexible centering.

Bit) element.

Whether it is leaf spring, torsion bar (shaft) spring or general spring.

Through the spiral projectile, one of its functions is that the driving force disappears.

After that, the valve core can automatically return to zero to ensure that the system is bright.

It's obviously in the middle.

The elastic force produced by the elastic centering element can.

Some or most of it becomes the resistance to the movement of the spool.

(4) tangential steering control valves are often equipped with negative cutting pressure.

The force-sensitive cavity is used to press the load through the reaction plunger in the cavity.

The resistance of the force to the movement of the spool.

Rotor is the key component of turbocharger.
