Below with reference to the accompanying drawings the fuel feeding Fuel Tanking Unit 10 of hydraulic cylinder according to the ... of the embodiment of the present invention is described.
As Figure 1-Figure 4, the fuel feeding Fuel Tanking Unit 10 of hydraulic cylinder according to the ... of the embodiment of the present invention includes shell 100, lives
Plug 200, elastic device 300 and oil pipe 400.
Shell 100 has cavity 110.Piston 200 is slidably disposed in cavity 110, and piston 200 divides cavity 110
It is divided into spaced fluid chamber 111 and power cavity 112.Elastic device 300 is located in power cavity 112, and elastic device 300 exists
The sliding in cavity 110 of piston 200 is driven during storing elastic potential energy and release elastic potential energy, and fluid chamber is changed with this
111 volume.One end of oil pipe 400 is connected to fluid chamber 111, and the oil of the other end of oil pipe 400 and the hydraulic cylinder
Mouth is connected.
The course of work of the fuel feeding Fuel Tanking Unit 10 of hydraulic cylinder according to the ... of the embodiment of the present invention is described below.
When compressing the hydraulic cylinder, by the piston rod force to the hydraulic cylinder, the hydraulic cylinder is set to be compressed, institute
The fluid stated in hydraulic cylinder flows to fluid chamber 111 by oil pipe 400, so that the pressure in fluid chamber 111 is increased, to push work
Plug 200 overcomes the elastic force of elastic device 300 to move.When discharging the hydraulic cylinder, elastic force of the piston 200 in elastic device 300
The lower movement of effect, and the fluid in fluid chamber 111 is pushed to the hydraulic cylinder by oil pipe 400, to improve the hydraulic cylinder
Interior pressure, to push the piston rod of the hydraulic cylinder to be restored to origin-location.
The fuel feeding Fuel Tanking Unit 10 of hydraulic cylinder according to the ... of the embodiment of the present invention makes piston 200 will by the way that piston 200 is arranged
Cavity 110 is separated into fluid chamber 111 and power cavity 112, and the elasticity dress that setting driving piston 200 moves in power cavity 112
Set 300.In this way when using the hydraulic cylinder supporting object, the fluid in elastic device 300 and fluid chamber 111 can be utilized total
It is all that the hydraulic cylinder provides power, to ensure buffering and support effect of the hydraulic cylinder to supported object.
Also, since when discharging the hydraulic cylinder, piston 200 pushes fluid under the elastic force effect of elastic device 300
Fluid in chamber 111 flows to the hydraulic cylinder, and the hydraulic cylinder is made to reset.The hydraulic cylinder can be made in elastic device in this way
300 and fluid collective effect under resetted, push piston 200 that can improve the position of piston 200 by elastic device 300
Variation range, to improve the change in location amplitude of the hydraulic cylinder, and can by the power of fluid transfer elastic device 300
With using fluid to the elastic force of elastic device 300 into row buffering, prevent the hydraulic cylinder when resetting with larger initial velocity,
Consequently facilitating operating personnel operate.For example, when using the Hydraulic Cylinder Pedestal Used chair, make the liquid by pushing seat
Fluid in cylinder pressure flows to fluid chamber 111, and pushes 200 elasticity of compression device 300 of piston, after seat is depressed into suitable position
Seat is fixed by seat lock, to realize the adjusting to seat position.When needing to adjust seat again, seat is unclamped
Chair is locked, and the release of elastic device 300 simultaneously exerts a force to piston 200, and the fluid in fluid chamber 111 is made to return to the hydraulic cylinder, thus will
Seat jacks up again, at this time since the elastic force of elastic device 300 is buffered by fluid, can quickly be bounced to avoid seat, from
And it is operated convenient for user.
Further, since push piston 200 using elastic device 300, compared to use fluid pump etc. other provide for fluid it is dynamic
The mode of power can not only save the structure for power supply, to save the cost of the fuel feeding Fuel Tanking Unit 10 of hydraulic cylinder, reduce liquid
The energy consumption of the fuel feeding Fuel Tanking Unit 10 of cylinder pressure, and due to being not necessarily to that fluid pump is arranged, the process of installation fluid pump can be saved, saved
Go to the space of installation fluid pump.
Further, due to providing power by elastic device 300, elastic force can be selected suitable according to actual conditions
Elastic device 300.Specifically, the power that can be in the axial direction undertaken by the way that the hydraulic cylinder is calculated, and according to described
The stress of hydraulic cylinder selects suitable elastic device 300.It is possible thereby to convenient for the elastic force of control elastic device 300, in order to control
Fuel feeding effect from the fuel feeding Fuel Tanking Unit 10 of hydraulic cylinder processed to the hydraulic cylinder, to further be convenient for improve hydraulic cylinder fuel feeding
The accuracy that Fuel Tanking Unit 10 controls the hydraulic cylinder.
Therefore, the fuel feeding Fuel Tanking Unit 10 of hydraulic cylinder according to the ... of the embodiment of the present invention can avoid the quick bullet of the hydraulic cylinder
