Summary of the invention
The utility model technical issues that need to address are, the application trouble that causes because of continuous oil supply that overcomes that the Pneumatic oil pump of existing technology exists provides the pneumatic filling pump of gap fuel feeding of a kind of low noise, energy-conservation, compact type.
The purpose of the utility model is achieved through following technical proposals: the pneumatic filling pump of a kind of gap oil feeding type; Comprise cylinder and oil cylinder; Said cylinder is the adjustable supercharging type standard cylinder that is provided with damping device, and said oil cylinder is provided with the inlet port and the pouring orifice of independent one-way only operation respectively; The cylinder body of said cylinder and the cylinder body of oil cylinder link into an integrated entity with link; The cylinder cavity axis of cylinder is coaxial setting with the cylinder cavity axis of oil cylinder; Coaxial the connecting as one of piston rod one end of one end of the piston rod of cylinder and oil cylinder, and cylinder is located at the position, top of oil cylinder.
Be connected the drive oil cylinder piston by bounce cylinder with the oil cylinder piston bar through cylinder piston rod and slowly promote, hydraulic oil is slowly sucked the oil cylinder cavity of resorption and is filled whole lower oil cavitie fully through inlet port thereby make the oil cylinder cavity of resorption form low pressure area generation suction; Through the pneumatic valve switch operation, be connected the drive oil cylinder piston by adjustable pressurized cylinder with the oil cylinder piston bar through cylinder piston rod and descend then, hydraulic oil through pouring orifice output, is so just formed an oiling process; Cylinder is knee-action constantly, and the oil outlet that makes oil pump is pressure oil output with gap.
As preferably, said cylinder piston rod and oil cylinder piston bar are for being threaded.
As preferably, the inlet port of said oil cylinder is provided with the one-way valve that guiding sucks, and the oil outlet of oil cylinder is provided with the one-way valve of guiding output.
As preferably, be provided with the enlarged openings of conical surface in the valve seat location of each one-way valve.The surface of contact that the enlarged openings of this conical surface can increase valve seat and flap to be to reduce prooving of valve seat amount, is that the flow resistance of pressure oil alleviates by means of enlarged openings simultaneously.
As preferably, the damping device of said cylinder is cooperated with the circular cone of the piston head end face of standard cylinder by the inboard counterbore of the loam cake that is located at the standard cylinder and constitutes the diameter at butt end of said circular cone and the equal diameters of said counterbore.When piston stroking upward when circular cone inserts said counterbore, along with circular cone deepens continuously, the matching gap between circular cone and the counterbore is more and more littler, the pressure air velocity of discharge that is enclosed in the counterbore becomes slowly, pressure further increases, and plays the effect to buffer piston.
The beneficial effect of the utility model is to be suitable for not having electricity, to make controllable type intermittence oil supplying device under the low noise, energy-conservation, environment that compact type requires; Can vertically install; Can control the flowing velocity of pressure, flow and the hydraulic oil of output hydraulic oil, simple to operate, have versatility.
