Description of drawings
Accompanying drawing 1 is singly organized plunger valve group's longitudinal profile structural representation for the present invention;
Accompanying drawing 2 is organized plunger valve group's longitudinal profile structural representation more for the present invention.
Embodiment
As shown in Figure 1, 2,
The plunger valve group 1 that the present invention arranges in the pump housing, centered by the power input shaft 2 of pump housing power equipment (as motor, diesel engine, petrol engine etc.), be provided with only represent corresponding a pair of two in the plunger valve 3(Fig. 1 that lays in the orientation such as a plurality of).Each plunger valve mainly is comprised of valve rod 31 and valve body 32.Valve body wall is provided with oil extraction inclined hole 33, and the oil extraction inclined hole connects the oil pocket 5 that oil drain passage leads to the pump housing, and oil pocket leads to the hydraulic equipment (not shown) by total oil exit pipe 4; The bottom of valve body is provided with oil-sucking hole 34.Oil extraction inclined hole lower end is provided with boss 331 with the place of communicating, valve body chamber, is placed with oil drainage hole steel ball 332 on boss; Oil-sucking hole 34 is provided with concave station 341, is placed with oil-sucking hole steel ball 342 on concave station.
The present invention and power input shaft 2 are connected with large footpath swash plate 7, path swash plate 8.The inclined-plane 71 of large footpath swash plate 7 is pressed in during rotation on the stem head of each plunger valve towards the below.The inclined-plane 81 of path swash plate 8 plays a supportive role to disk 9 during rotation towards the top, and disk 9 imposes on the different pressures of each plunger stem head during with large footpath swash plate 7 rotation, promote and each plunger valve rod that descends, with complete each plunger valve body into and out of oily operation.
Shown in Figure 2 again, for the present invention establishes the embodiments that organize the plunger valve groups more.Plunger valve group 1 in figure is three groups, arranges centered by pump housing power input shaft 2 successively, is provided with connecting cylinder 6 between each group, will organize the plunger valve group more and connect into the whole pump housing.Connecting cylinder is provided with the filler opening 61 that is connected with the pump externally mounted fuel tank, and it is positioned at that the bottom of the one group of plunger valve group valve body in below has pump fuel tank 10, and communicates with pump externally mounted fuel tank (not shown) by the filler opening 61 of connecting cylinder.
Assembly bearing involved in the present invention is not expression in the drawings all.
Below in conjunction with accompanying drawing, brief description working procedure of the present invention:
The power input shaft 2 of two inclined plate structure plunger pump of the present invention drives the large footpath swash plate 7, the path swash plate 8 that are connected with axle and rotates.As Fig. 1, when the inclined-plane minimum point of large footpath swash plate 7 is pressed on a certain plunger stem head, this plunger valve rod is operation downwards, and this position that drives disk 9 is in low level, and another plunger valve rod of the opposite location that claims with this plunger valve pole pair is in uplink state; Simultaneously, due to the effect of the peak on path swash plate inclined-plane 81, the plunger that makes disk 9 drive this place up moves, and another plunger valve rod of the opposite location that claims with this plunger valve pole pair is in downstream state.Oblique opposite because of path swash plate 8 and large footpath swash plate 7 is when therefore path swash plate 8 rotates with rotatingshaft, in support disk 9, dodge out again the space of large footpath swash plate 7 rotations.With in like manner upper, remaining each plunger valve rod will be between linear up or decline of transmitting.When the plunger valve valve rod moved up, oil-sucking hole steel ball 342 was picked up, and oil-sucking hole sucks fluid; During to bottom offset, oil-sucking hole steel ball 342 is adjacent in the oil suction aperture when the plunger valve valve rod, and the fluid in valve pocket is the communications centre oily inclined hole steel ball 332 that begins to rehearse, and the fluid in valve pocket is discharged from oil extraction inclined hole 33, enters pump housing oil pocket and oil outlet tube.Be provided with chamfering man-hour because boss or concave station add, thereby steel ball drops on oil drainage hole or oil-sucking hole and all good sealability can be arranged.The present invention is by each group plunger valve group's plunger valve rod to-and-fro motion again and again, and high pressure oil exports the engineering hydraulic equipment to from oil outlet tube to make the oil outlet of plunger pump have continuously, thereby reaches the goal of the invention of expection.
