ABSTRACT:
Herein disclosed is a trigger type liquid injector which includes a body mounted to stand on a liquid container, an injection cylinder extending in a horizontal direction from the upper portion of the body, and pumping means arranged at such an interior angle as is defined by the body and the injection cylinder. There is mounted in the base of the injection cylinder a discharge valve which is opened by the internal pressure in a pump chamber when this pressure exceeds a predetermined level. There is mounted on the front portion of the injection cylinder a nozzle cap which can change the states of the liquid being injected. The pumping means is actuated by the engagement between a recessed portion formed in a piston member and a trigger.
