Abstract

A pump unit (10), which includes (a)an elongated cylindrical housing (12) closed at both ends by a first end cover (22) and a second end cover (20) respectively; (b)a first cylinder (16) provided in the housing and extending at opposite ends through both end covers of the outer housing; (c)a first one-way valve (26) provided at one end of the first cylinder at or near the first end cover, which valve is adapted to open for allowing liquid to flow into the first cylinder when suction is applied to this valve; (d)a second one-way valve (30) provided at the other end of the first cylinder at or near the second end cover, which valve is adapted to open to allow liquid to flow out of the cylinder when pressure is applied to this valve; (e)at least one first aperture (32) in the first cylinder leading into a chamber (14) defined by the housing; (f)a second cylinder (18) provided in the housing, of which its end directed to or at the first end cover of the housing is closed; (g)a reciprocatingly arranged piston rod (52) extending through the second end cover of the housing into the second cylinder; (h)a piston (58) attached to the piston rod and being slidably mounted in the second cylinder; (i)at least one second aperture leading into the second cylinder from the chamber in the housing so that movement of the piston away from such second aperture(s) in the second cylinder towards the closed end of the second cylinder causes suction to be applied for sucking liquid through the first one-way valve into the first cylinder, thereafter into the chamber and then into the second cylinder through the second aperture(s), whilst the second one-way valve is closed, and movement of the piston in an opposite direction from the closed end of the second cylinder towards the second aperture(s) causing the first one-way valve to close and the second one-way valve to open so that liquid is displaced from the second cylinder through the second aperture(s) into the chamber and thence through the first aperture(s) into the first cylinder and through the second one- way valve to be discharged via a discharge pipe (72).
