For the valve body assembly 2100, there are various embodiments,

referring to fig. 5, one embodiment a of a valve body assembly 2100:

valve body assembly 2100 includes upper housing 2110, lower housing 2120, main spool 2130, spring 2140, and rubber check spool 2150; the upper and lower shells 2110 and 2120 are fixedly connected and form an oil cavity therebetween, an oil outlet 2111 communicating with the oil cavity is provided at an end of the upper shell 2110, and an oil inlet 2121 communicating with the oil cavity is provided at an end of the lower shell 2120. Main spool 2130 fits within the oil cavity in sliding motion and sealing engagement with the oil cavity sidewall, main spool 2130 dividing the oil cavity into an upper oil cavity 2161 and a lower oil cavity 2162, the upper volume of lower oil cavity 2162 being greater than the lower volume. Spring 2140 is mounted between main spool 2130 and upper housing 2110 for providing a return spring force and for maintaining main spool 2130 in interference with rubber check spool 2150 against oil inlet 2121. The end of the main valve spool 2130 near the rubber check valve spool 2150 is provided with a switching port 2131, and the end of the rubber check valve spool 2150 closes the switching port 2131 when abutting against the switching port 2131. The side wall of main valve element 2130 is provided with a mounting groove 2132, and mounting groove 2132 is fitted with a sealing ring 2133.

With this structure, the rubber check valve 2150 can be turned on in one direction by the hydraulic pressure, that is, the hydraulic pressure is turned on from bottom to top, and the hydraulic pressure is sealed in the opposite direction.

Working principle: the oil inlet 2121 is slightly jacked up by the rubber check valve spool 2150 under the action of lubricating oil pressure, and the oil in the upper oil cavity 2161 is pushed out of the oil outlet 2111 and the lower oil cavity 2162 is filled with oil because the pressure is greater than the sealing of the umbrella-shaped skirt edge 2151 at the upper edge of the rubber check valve spool 2150 and the acting force formed by the bottom surface of the main valve spool 2130 and the bottom surface of the rubber check valve spool 2150 under the action of lubricating oil pressure is greater than the elastic force of the spring 2140, so that the main valve spool 2130 and the rubber check valve spool 2150 are jacked up at the same time. When oil inlet 2121 loses pressure, main spool 2130 is pushed downward by the reaction force of spring 2140, forcing rubber check valve spool 2150 out of main spool 2130 due to the greater volume above lower oil chamber 2162 than below, and the oil in lower oil chamber 2162 enters upper oil chamber 2161 through transition port 2131 until main spool 2130 again engages rubber check valve spool 2150.
