Abstract (en)
A lubrication system comprises a pair of pumps (12,14), supplied from a common inlet and being capable of being connected to a common outlet (24). When pressure in the outlet rises, control valve (28) can displace against spring (30) to provide a flow path direct to exhaust through the valve, so that the outlet (20) is fed only from the pump (12). <IMAGE>
