Abstract

A pumping device includes a main body having a passage defined therein through which air passes and a head connected to the main body. A retainer is slidably received in the head and includes a first compartment defined therein for receiving a spring. An end of the retainer includes a conical recess defined therein. A nozzle is slidably mounted in the end of the retainer and includes an end attached to the spring. A nozzle head is securely mounted in an end of the head and includes a second compartment defined therein and in communication with the first compartment via the nozzle. The nozzle head includes a hollow conical section for engaging with the conical recess of the retainer. A lever is provided for switching the retainer between a first operative position in which the first compartment communicates with the passage and a second inoperative position in which the first compartment does not communicate with the passage.
