A steam trap ( 1 ) is provided comprising a chamber ( 8 ) having a substantially cylindrical sidewall, an inlet 20 provided towards the upper end of the sidewall, and an escape aperture ( 16 ) provided at its base. The inlet ( 20 ) introduces the fluid into the chamber ( 8 ) in a manner to promote a rotational flow of the fluid in the chamber ( 8 ), so as to create a low pressure location upstream of the escape aperture ( 16 ) to restrict the discharge rate of the aperture ( 16 ).
