A pump for dispensing liquids, for example for an ironing spray or a pharmaceutical spray, has a multidirectional delivery by arranging that the barrel 2 of the pump is rotatable in relation to a base 1 (to which it is sealed) to bring a delivery path 25 selectively into engagement with either or any of two or more delivery passages 28, 29. A handle 31 facilitates this. The pump can have main and auxiliary pistons 3 and 12, the latter only having a short travel and moving with the main piston only at the start of its stroke to open and close the delivery path. A gasket 22 against which it seats in the rest position may also form the abutment for a return spring 21. <IMAGE> |
