Beschreibung
Zusammenfassung:	A hydraulic circuit includes a pump in fluid communication with a reservoir containing a liquid to be pumped. The pump includes an inlet and an outlet. The hydraulic circuit also includes a venturi pump in fluid communication with the reservoir and with the outlet of the pump, and an injection valve including a cooling feature. The injection valve is in fluid communication with the outlet of the pump, and is configured to dispense liquid supplied to the injection valve by the pump. The cooling feature is in fluid communication with the venturi pump. The pump is configured to produce a first flow of liquid, and the hydraulic circuit is configured to supply a first portion of the first flow of liquid to the injection valve for dispensing by the injection valve and a second portion of the first flow of liquid to the venturi pump.
