Hole, is provided with interior oil-in, interior unloading port, outer oil-in and outer unloading port in upper installing hole, operating cylinder is installed on installation
Hole, operating cylinder includes inner core and urceolus, and interior oil-in and interior unloading port are positioned at inside inner core, outer oil-in and outer unloading port position
Folder intracavity in inner core Yu urceolus；The side of base is provided with the valve opening of a level, described outer oil-in, interior oil-in and oil suction
Mouth, by passage and valve opening UNICOM, the middle part of inlet port UNICOM valve opening, the both sides of oil-in UNICOM outer, interior valve opening, sets in valve opening
There are two check valves, two check valves to be spaced folding successively, formed and flowed to inlet port by outer oil-in, then flowed to interior oil-feed by inlet port
The passage of mouth；The side of base is additionally provided with unloading hole, and described inside and outside unloading port is respectively by passage UNICOM unloading hole, described off-load
Unloader it is provided with in hole.
Being additionally provided with spout hole on described base, spout hole is arranged at valve opening homonymy, and described spout hole UNICOM inlet port is with interior
Passage between oil-in.
After taking above technical scheme, the invention have the benefit that by pedal drive actuator cylinder from outer shell and
Make a gift to someone again in inner casing after space oil suction between cylinder, promote piston to stretch out, complete the rising of work top.Parking brake pulls unloader work
The cylinder making oil cylinder completes off-load after outer shell UNICOM.Base is provided with multiple hydraulic fluid port, is provided with plurality of passages, by oil circuit in base
It is integrated in base, it is to avoid use pipeline, simplifies structure.Two check valves it are provided with in valve opening, when actuator cylinder oil suction,
Outer oil-in flows to the passage of inlet port and opens, and has and flows into actuator cylinder from outer shell；When actuator cylinder send oil, inlet port flows to
The passage of interior oil-in is opened, and the oily ultromotivity oil cylinder in actuator cylinder is made a gift to someone cylinder, promotes cylinder piston to stretch out, hydraulic control
Simple and reliable.
