Problems solved by technology
The engine proportional control hydraulic solenoid valve product in the prior art requires seven oil holes because of the unreasonable product structure of the front valve body, which increases the processing cost and the interference of the oil circuit on the response time. At the same time, the mass of the moving parts is too large. making the response slower

Embodiment Construction
[0026] Below with reference to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention, such as the shape, structure, mutual position and connection relationship between the various parts, the role and working principle of the various parts, etc., will be further described. Detailed instructions:
[0027] as attached figure 1 — attached Figure 7 As shown, the hydraulic valve structure includes a hollow valve body 3 and a hollow shell 9, and the end face of the valve body 3 is fixedly connected with the end face of the shell 9. 4. A plurality of oil holes 12 are set on the valve body 3, and the coil assembly 10, as well as the front magnetic pole 7 and the magnetic core assembly 8 are installed in the casing 9. The component assembly 10 is connected with the control part 35 that controls the on-off of the coil assembly assembly 10 .
[0028] Preferably, the valve body 3 is configured as a structure manufacture...

The invention provides an engine proportional control hydraulic valve structure applicable to the field of automobile engines. A spring (1) and a spool (4) are sequentially arranged in a valve body (3) of a hydraulic valve, a plurality of oil holes (12) are formed on the valve body (3), a coil assembly (10), a front magnetic pole (7) and a magnetic core assembly (8) are arranged in a housing (9), the front magnetic pole (7) and the housing (9 ) are in an attaching structure, and the coil assembly (10) is connected with a control member (35). According to the proportional control hydraulic valve structure, the response speed and the reliability of a solenoid valve are improved, and the applicability of the proportional control solenoid valve is wide. The proportional control hydraulic valve structure can be simultaneously mounted in an engine cylinder head with a peripherally uniformly-distributed oil-way structure by replacing the front valve body portion.
Description
technical field [0001] The invention relates to the field of automobile engines, and more specifically relates to an engine proportional control hydraulic valve, which is used to control the opening and closing timing of the intake valve or exhaust valve of the engine. Background technique [0002] Engine variable valve timing technology (VVT, Variable Valve Timing), as a new energy-saving and efficiency-enhancing technology, has been widely used in modern cars in recent years. As the control component of the engine variable valve timing system actuator - the proportional control hydraulic solenoid valve is also an essential component, but because the proportional control hydraulic solenoid valve requires high response speed and high reliability requirements, so It has always been a key component in engine variable valve timing technology. The engine proportional control hydraulic solenoid valve product in the prior art requires seven oil holes because of the unreasonable p...
