PURPOSE:To enlarge the application scope of the captioned equipment by connecting a change-over valve mechanism, which switches the supply of fluid to a large-diameter cylinder, to a large-dia. cylinder via a switching mechanism and connecting the piston of a small-dia. cylinder to the connecting rod of the large- dia. piston. CONSTITUTION:The introduction pipe 26 and the discharging pipe 27 of a large- diameter cylinder 30 are connected to a change-over valve mechanism 1, while the large-dia. cylinder 30 is connected to the change-over valve mechanism 1 via a switching machanism 32. A small-dia. cylinder 52 is provided in the neighborhood of the large-dia. cylinder 30 while the connecting rod 37 of a large-dia. piston 31 is connected to the small-dia. piston 53 of the small-dia. cylinder 52. The small-dia. cylinder 52 is connected to an introduction pipe 21 via introduction-check valves 56 and 57 and to a high pressure discharge pipe 60 via discharge-check valves 58 and 59. With this contrivance, the pressure of low pressure gas or liquid is increases, thereby eliminating the necessity for using electricity or an internal combustion engine. Thus, this equipment can widely be used at a height or at a place subject to explosion. |
