Abstract:
A portable chilling sleeve for controlling the temperature of a hollow cylinder having an outer wall and an inner surface, thereby adjusting the size of the diameter of the outer wall, comprising:an upper body having a sleeve leg insertable into said hollow cylinder, the upper body having inlet and outlet ports, wherein said body has a projection and a lower end cap, which in operation contact said outer walls of said hollow cylinder, the projection and lower end cap each having an o-ring seal for preventing leaks; a higher pressure chamber formed within the sleeve leg and in fluid communication with the inlet port; a lower pressure chamber, formed in operation between the sleeve leg and the inner surface of said hollow cylinder, the lower pressure chamber separated from said higher pressure chamber by escape holes in the sleeve leg and in fluid communication with the outlet port; and pump means for regulating intake into said inlet port and exhaust out of said outlet port, wherein said rate of exhaust release controls the temperature and size of the outer wall of said hollow cylinder.
