Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
The pressurized machine that surges of one as shown in Figure 1, comprise have inner chamber valve body 1, there is the oil outlet seat 2 of oil outlet 2-1, described valve body 1 front end has bump 1-3, oil outlet seat 2 has engage sleeves and is connected on the inner fovea part 2-2 of bump 1-3 periphery, in bump 1-3, offer through hole 1-4, valve body 1 is connected with the combination of bump 1-3 by inner fovea part 2-2 with oil outlet seat 2.
Valve body 1 rear end offers filler opening 1-1 and lower filler opening 1-2, in the inner chamber of valve body 1, slide and be provided with piston 3, on piston 3, be connected with the piston rod 4 being structure as a whole with piston 3, piston rod 4 is slidably matched with through hole 1-4, the rod chamber 5 of upper filler opening 1-1 communication with cavity, the rodless cavity 6 of lower filler opening 1-2 communication with cavity, described through hole 1-4 communicates with rod chamber 5.
Between described piston rod 4 external parts and the interior edge face of inner fovea part 2-2, form the high-voltage oil cavity 7 being communicated with rod chamber 5, rod chamber 5 is communicated with high-voltage oil cavity 7 by the oil circuit being located in piston rod 4, oil circuit between high-voltage oil cavity 7 and oil outlet 2-1 is provided with high pressure one-way valve 8, the oil circuit that leads to rodless cavity 6 is provided with low pressure check valve 9, is provided with and controls the oil feed non-return valve 12 that rod chamber 5 is communicated with high-voltage oil cavity 7 in piston rod 4.
On connecting the oil circuit of filler opening 1-1 and connect under between the oil circuit of filler opening 1-2, be provided with oil circuit control 10, oil circuit control 10 is provided with the control spool 11 of opening low pressure check valve 9 in the time of upper filler opening 1-1 oil-feed, specifically, described control spool 11 is T font, low pressure check valve 9 is located at nearly oil circuit control 10 ends, and the straight-bar portion that controls spool 11 can depress low pressure check valve 9 and rodless cavity 6 is communicated with lower filler opening 1-2 in the time of upper filler opening 1-1 oil-feed.
Working principle is summarized as follows: upper and lower filler opening 1-1,1-2 are by selector valve control oil-feed and the fuel-displaced order of system.Instantly filler opening 1-2 oil-feed, when upper filler opening 1-1 is fuel-displaced, low pressure oil is backed down low pressure check valve 9 and is entered in rodless cavity 6 from oil circuit, to control upwards jack-up of spool 11 simultaneously, closing control oil circuit 10, the low pressure oil promotion piston 3 entering in rodless cavity 6 from lower filler opening 1-2 moves right, it is fuel-displaced that low pressure oil in while rod chamber 5 is back to upper filler opening 1-1 through oil circuit, piston 3 drives piston rod 4 to move and promotes the oil formation high pressure in high-voltage oil cavity 7, breaks through high pressure one-way valve 8, fuel-displaced from oil outlet 2-1; When upper filler opening 1-1 oil-feed, when lower filler opening 1-2 is fuel-displaced, low pressure oil is through oil circuit control 10, promoting to control spool 11 presses down low pressure check valve 9 and opens low pressure check valve 9, low pressure oil in rodless cavity 6 from low pressure check valve 9 flow out through filler opening 1-2 fuel-displaced, simultaneously low pressure oil enters in rod chamber 5, backs down oil feed non-return valve 12 and enters in high-voltage oil cavity 7, waits for that next piston rod 4 promotes and forms after high pressure oil fuel-displaced from oil outlet 2-1.
