Valve for pump

#1. Field of Invention

#The present invention is related to a valve for a pump.

#2. Related Prior Art

#The present invention is described through detailed illustration of embodiments referring to the attached drawings wherein:

#FIG. 1 is a cross-sectional view of a valve according to a first embodiment of the present invention in communication with a flexible pipe extending from a pump, showing the valve in a position for pumping air through an ordinary nozzle;

#FIG. 2 is similar to FIG. 1 except for showing the valve in a position for pumping air through an ultra-high pressure nozzle;

#Referring to FIGS. 1 and 2, a valve according to a first embodiment of the present invention includes a housing 10, an ordinary nozzle 31, an ultra-high pressure nozzle 32 and a switch 20.

#The housing 10 defines a chamber 11, a hole 12 communicated with the chamber 11, an inlet channel 14 in communication with the chamber 11 and an outlet channel 15 in communication with the chamber 11. The inlet channel 14 extends through a joint 13 projecting from the housing 10 and includes a first end this is open to the external of the housing 10 and a second end that is open to the chamber 11. The joint 13 includes a root and a tip thinner than the root. The tip of the joint 13 can be inserted in an end of a flexible pipe 17 leading from a pump (not shown). Thus, air can be provided from the pump to the valve. A ring secured to the end of the flexible pipe 17 can be engaged with the root of the joint 13. Thus, communication of the pump with the valve is ensured.

#The outlet channel 15 extends through a joint 16 projecting from the housing 10 and includes a first end that is open to the chamber 11 and a second end that is open to the external of the housing 10. The ordinary nozzle 31 is received in the second end of the outlet channel 15. A ring 19 is engaged with an end of the joint 16, thus retaining the ordinary nozzle 31 in the second end of the outlet channel 15.
