Abstract: A fluid control system for use with vehicles, in particular, trailers, includes a branch conduit which is to be connected to a pressure supply line and a control line to enable priming of the control line so that signals generated upon application of the vehicle brake pedal are more quickly transmitted to the trailer brakes. This overcomes problems associated with delay in application of the trailer brakes. An electrically operated solenoid valve controls fluid flow through the branch conduit so that upon application of the vehicle brake pedal the solenoid valve is operated to open the branch conduit to allow pressurized fluid to flow from the supply line to the control line for a predetermined time period to prime the control line. Pressurized fluid from the branch supply conduit is directed longitudinally down the control line by a longitudinally arranged outlet so that substantially all of the fluid is directed to backfill the control line.

Abstract: A dispenser has a first container (12) for containing a component C and a cavity (30) for receiving a separate cartridge (60). A first piston (34) is received in the container (12) and a second piston (78) is received in the cartridge (60). A blade (48) extends between the piston (34) and piston (78) for slicing the separate cartridge (60) as the pistons move so that the component C and a second component C1 in the separate cartridge (60) are expelled from the dispenser. A valve arrangement (100) can be coupled to an outlet (18) for the dispenser in order to dispense the components C and C1 and a flexible sleeve (50) may be arranged in the container (12) between a sidewall of the container (12) and the piston (34) for sealing any space between the piston (34) and the sidewall of the container (12).
