Automatic reciprocating -type supercharger is used in nonoculture

The utility model provides an automatic reciprocating -type supercharger is used in nonoculture, including supercharge unit, automatic reversing control valve, outside high voltage output mouth, oil return opening and the high -pressure hydraulic fluid port of intercommunication to and the return path and the high -pressure passageway of connection oil circuit, supercharge unit includes low pressure plunger and high -pressure plunger, high pressure plunger lower extreme with low pressure plunger upper end links to each other, and the top formation high pressure chest of high pressure plunger the top formation oil return chamber of low pressure plunger the below of low pressure plunger forms the low pressure chamber, the high pressure chest is through first check valve and high voltage output mouth intercommunication. Have simple structure, the processing cost is low, and control is simple, can realize moving certainly automatic pressure boost, and the while is small, easy maintenance's advantage. 本实用新型提供种单作用自
