Abstract
A fluid injecting system for injecting fluid into soil is disclosed, the system comprising a tank for receiving and from which is discharged the fluid, mixing apparatus in the tank for mixing the fluid, a transfer pump in fluid communication with the mixing tank, a high pressure pump, the transfer pump in fluid communication with the high pressure pump for pumping fluid from the mixing tank to the high pressure pump, sequencing pumping apparatus for providing sequential charges of fluid to a nozzle apparatus, and nozzle apparatus with at least one nozzle through which fluid is injected into the soil, the sequencing pumping apparatus in fluid communication with the nozzle apparatus. In one aspect an accumulator accumulates a charge of fluid which is supplied to the nozzle apparatus. In one aspect the sequencing pumping apparatus includes a pneumatically controlled sequencing control valve which responds to precise pressure changes to control the duration of fluid pulses.
