Abstract
The utility model discloses a two-position four-way hydraulic control switch valve which comprises a valve body, a valve jacket, a valve core shaft and a pressure adjustor. The valve body is provided with a liquid inlet of first pipe passage, a liquid outlet of first pipe passage, a liquid inlet of second pipe passage and a liquid outlet of second pipe passage. The valve jacket is inserted into the valve body. The valve core shaft can slide in the valve jacket in the left-and-right direction. A left projected shaft, a first valve core, a shaft journal, a second valve core and a right projected shaft, which are included in the valve core shaft, form an integral component. A pressure adjustment spring presses the valve core shaft to the left end of the valve jacket. The first valve core blocks the liquid outlet of the first pipe passage. Simultaneously the second valve core opens a passage from the liquid inlet of the second pipe passage to the liquid outlet of the second pipe passage. When the liquid inlet pressure of the chamber in which the liquid inlet of the first pipe passage is provided is larger than the pressure of the pressure adjustment spring, the valve core shaft slides rightwards, and the second valve core blocks the liquid outlet of the second pipe passage. Simultaneously the first valve core opens a passage from the liquid inlet of the first pipe passage to the liquid outlet of the first pipe passage.
