Abstract: An undercarriage washing assembly for washing the undercarriage of a vehicle includes a spray block 12 that has a fluid input 14, a first fluid output 16 and a second fluid output 18. The fluid input 14 is fluidly coupled to a fluid source 20 comprising a handle of a pressure washer. The first fluid output 16 is oriented to lie along a line oriented at an upward angle with respect to the fluid input 14. In this way the first fluid output 16 can spray fluid upwardly from the spray block 12. The second fluid input 14 is oriented to lie along a line is oriented at an upward angle with respect to the fluid input 14 to spray fluid upwardly from the spray block 12.

Abstract: The pump of the invention has application as a fuel pump for delivering fuel over a range of flow rates to an internal combustion engine. The pump may however be employed in many other applications, such as chemical applications, medical applications and hydraulic applications for example, particularyly where fine control of the fluid flow rate and a fast response from the pump to flow rate change requirements is necessary.
