Substance Dispensing System

摘要

A substance dispensing system that includes a hydraulic drive system is disclosed. The hydraulic drive system includes a hydraulic valve having a variable pressure setting, the hydraulic valve operable between a closed position in which a hydraulic pump moves hydraulic fluid to a hydraulic cylinder and an open position in which the hydraulic pump moves the hydraulic fluid to a hydraulic reservoir. The substance dispensing system of the present disclosure provides a system that recirculates hydraulic fluid in a hydraulic drive system instead of recirculating a substance back to a container via a pump. The substance dispensing system of the present disclosure allows for precise, accurate, and instantaneous control of an external force in a substance dispensing system.

1. A substance dispensing system, comprising a drive system including a valve having a variable pressure setting, the valve operable between a closed position in which the drive system moves a fluid to an actuation member via a supply line thereby actuating the actuation member and an open position in which the drive system recirculates the fluid to a reservoir via a relief line thereby relieving the fluid moved to the actuation member and stopping movement of the actuation member.
