Abstract

A housing selectively encloses a nozzle. The housing has a body that partially defines an interior space in which the nozzle is configured to be disposed. The housing also includes a cover assembly that selectively blocks a first aperture of the body and further defines the interior space. Additionally, the housing has a piston that is disposed in the interior space and secured to the nozzle. The piston defines a gas inlet, a liquid inlet, and an outlet fluidly connected to both the gas inlet and the liquid inlet. The housing further includes a biasing member attached to the piston. The biasing member is configured to exert a biasing force that biases the nozzle to a retracted position. The biasing member is further configured such that when pressurized gas flows through the body, the biasing force is overcome such that the nozzle is disposed in an extended position.
