Abstract

173,438. Dickie, C., and Crerar, L. P., (trading as Smith, A. & R.). Jan. 15, 1921. Check or non-return valves. - A non-return valve particularly applicable for use in ships' bilges and of the kind having a hollow cylindrical valve member 1 guided by ribs 2 in the casing has the top of the valve seat formed in a continuous curve with the valve chamber so that no pockets are formed for the collection of grit. The hollow valve tends to float in the liquid so that it comes gently to its seat.
