<p>A pressure inducing device 10 for pressurizing a substance is provided. The device 10 includes a body 12, a pressure chamber 14 defined by the body 12 and an inlet 18 leading into the pressure chamber 14 through which inlet 18 a substance to be pressurized can be fed into the pressure chamber 14. A piston 22 is arranged to travel along the pressure chamber 14 to pressurize a substance in the pressure chamber 14. An outlet 20 leads from the pressure chamber 14. A blocking member 28 is arranged to open the outlet 20 after the substance has been pressurized in the pressure chamber 14 thereby to permit the pressurized substance to expel under pressure through the outlet 20 in response to opening the outlet 20.</p> |
