ELECTRO-HYDRAULIC SYSTEM WITH FLOAT FUNCTION |
| 摘要 |
A method of controlling a float function of a cylinder 25 having a first side and a second side includes connecting the second side of the cylinder to a reservoir 15; connecting the first side of the cylinder to an output of a pump 20 and to the reservoir; and supplying an amount of flow from a pump less than an amount supplied by the pump under loaded conditions. A three-position directional control valve 30 having a pump port, a reservoir port, a first cylinder port, and a second cylinder port may be provided to effectuate aspects of this method. |

1. A method of controlling a float function of a cylinder having a first side and a second side, the method comprising:
connecting the second side of the cylinder to a reservoir; connecting the first side of the cylinder to an output of a pump and to the reservoir; and supplying an amount of flow from a pump less than an amount supplied by the pump under loaded conditions, thereby enabling a float function of the cylinder while the limited amount of flow delivered by the pump is discharged to tank. |
