Abstract
A fluid flow control device (10) which is employed in
conjunction with a fluid pump (12) and which functions to
restrict reverse flow of liquid which is induced by the fluid
pump to flow in a forward direction through the device from a
source (11) of the liquid. The device comprises a housing (20
or 50) which contains first and second chambers (21 and 22 or
51 and 52), and a tube (26 and 37 or 54 and 60) is located in
each of the chambers. The tubes (26, 37, 54 and 60) define fluid
passageways (27, 36, 55 and 61) through which the liquid is
induced to flow in passing into the resoective chambers (21,
22, 51 and 52), and the tubes extend upwardly through the
respective chambers to a level above the level of liquid which
is contained in the chambers. Valve members (30, 39, 59 and
63) are located at the upper end of the respective tubes (26, 37,
54 and 60), the valve members providing for forward flow of
liquid into the chambers from the respective tubes and serv
ing to prevent the liquid from leaking in a reverse direction
along the fluid passageways (27, 36, 55 and 61). A control port
(32 or 64) enters the housing (20 or 50) and is connectable to
the fluid pump (12) for the purpose of applying alternating
negative and positive pressurisation to the chambers
whereby the liquid is induced to flow into and through the
chambers.
