Abstract: The present disclosure relates to a valve assembly, in particular for use in a tire inflation system, the valve assembly comprising: a valve body comprising a first fluid port and a second fluid port; a piston disposed at least partially within the valve body and configured to be moved relative to the valve body between an open position and a closed position, wherein when the piston is in the open position the first fluid port is fluidly connected with the second fluid port, and wherein when the piston is in the closed position the first fluid port is fluidly isolated from the second fluid port, wherein when the piston is in the open position the first fluid port and the second fluid port are fluidly connected with one another via a fluid channel extending through the piston. The present disclosure further relates to a tire inflation system including said valve assembly.

Abstract: A cartridge hand pump is disclosed. The cartridge hand pump comprises a housing; a lever extending from the housing; a cylinder provided in the housing wherein the cylinder is connected to a supply passage for receiving hydraulic fluid and to an actuator passage for sending pressurised hydraulic fluid; and a piston slidably positioned in the cylinder, the piston being operably connected to the lever for movement between a first position and a second position wherein the movement of the piston from the first to the second position sends pressurised fluid to the actuator passage characterised by a pressure relief valve accomodated in the housing wherein the pressure relief valve is in communication with the actuator passage such that pressurised hydraulic fluid is discharged through the pressure relief valve when pressure in the actuator passage exceeds a predetermined value.
