Abstract

A lubrication system 600 for an i.c. engine (110 Fig 1) has a variable displacement oil pump 605, piston oil jet cooling 700, and oil flow control. A pump inlet 635 connects to a sump 610, a pump outlet 640 connects to a main gallery 615, and oil pressure in primary and secondary control chambers 675, 680 controls pump displacement. The piston cooling jets are connected to an auxiliary gallery 695 having an associated control valve 710 with at least four ports. The first port 720 connects to the secondary control chamber, the second port 725 connects to the auxiliary gallery, the third port 730 connects to the main gallery, and the fourth port 735 connect­s to the oil sump 610. The valve has a valve member for interconnecting the ports, moveable between a first and second position, such that in the first position, the third port is connected to the second port and contemporaneously the first port is connected to the fourth port, and the second position, in which the second port is disconnected from the third port and contemporaneously the third port is connected to the first port.
