Abstract: An air pressure regulator for a dehider includes a valve to open and close the flow of pressurized air in an air inlet, a first spring urging the valve in the direction of air flow through the inlet to close the valve, a plunger operable to move the valve from a closed to an open position against the direction of air flow, a piston connected to the valve exposed to the air flow, and a second spring between the piston and the plunger. Upon depressing the plunger, the second spring urges the piston to open the valve against the air flow direction to permit pressurized air to flow through the regulator. The maximum allowable air pressure through the regulator is determined by spring forces of the first and second springs and resistance of the piston to the flow of air through the valve.
