The present disclosure relates to an apparatus (10) for pressurizing a first substance, such as a liquid, gas or particulate material, to a pressure substantially equal or similar to the pressure of a second substance, i.e. a reference substance. The pressure of the reference substance may be transient so the pressure of the first substance must be varied accordingly. The present disclosure includes a bladder (71) disposed within a sealed can (40), an inlet passage (24a) in communication with the interior (41) of the can and an outlet passage (26a) in communication with the interior of bladder (71). The reference substance may be directed into the interior (41) of the can (40) via the inlet passage (24a) and pressurizes the bladder (71) and thus the first substance stored therein, thereby causing the first substance to be expelled via the outlet passage (26a) with a pressure substantially corresponding to that of the reference substance. Many applications exist that require two substances to be of a similar pressure. For example, an engine may be adapted to run on low lubricity fuel provided a pressurized lubricant is introduced to the pressurized fuel before being directed towards the injector. |
