Abstract
An apparatus for flow control and shutoff comprises a body having a chamber, an inlet and an outlet, the inlet and the outlet in fluidic communication with the chamber; the said apparatus for flow control and shutoff further comprises a flow regulator comprising a channel and the flow regulator rotatably fit in the chamber, such that the flow regulator is rotatable between a first rotational position and a second rotational position and that the channel is in fluidic communication with at least one of the inlet and the outlet; the said apparatus for flow control and shutoff further comprises a lever operably connected to the flow regulator such that the lever urges the flow regulator to rotate between a first rotational position and a second rotational position in the chamber when a user of the apparatus pushes the lever. At the first rotational position, the channel is not in fluidic communication with at least one of the inlet and the outlet, such that fluidic communication between the inlet and the outlet is blocked. The flow regulator is operable to regulate a flow rate between the inlet and the outlet when the flow regulator is rotated between the first and the second rotation…
