An apparatus (10) for delivering metered amounts of a first fluid, such as a lubricating oil, to a remote location comprising a metering plate (36) coupled to a drive (18) for moving the metering plate between a first position in which a fluid receptacle in the metering head is filled with fluid and a second position in which the filled receptacle is placed between first and second ports for transfer of the fluid into and through a delivery line (28). The first port provides a source of a carrier fluid to drive the first fluid, while the second port is coupled to a delivery line to the remote location. The first and second ports form a portion of a manifold assembly (32, 34), which in conjunction with the metering plate comprise a metering head (figure 2). The metering head may be submerged in a reservoir whereby the receptacle is filled with a first fluid without the need for pumps or pressurization of the reservoir. |
