Abstract
An accumulator is added in-line with a valve on an agricultural machine and downstream of the valve. The valve is controlled to apply liquid material to a field over which the machine is traveling.
Claims20
A mobile agricultural machine, comprising:
- a ground engaging element that carries the machine over a field;
- a valve, having an inlet end configured to be connected to a source of liquid, under pressure, to be applied to the field and an outlet end;
- and
- an application assembly having a proximal end connected to the outlet end of the valve and having a distal end through which the liquid passes to be applied to the field, the application assembly defining a conduit between the proximal end and the distal end, and having an accumulator disposed along the conduit to at least partially absorb pressure in the conduit when the liquid under pressure is in the conduit.
