<p>Pressure gauge (1) for pumps (2), particularly hand pumps for bicycles, motorcycles or the like, including a cylinder (13) sealingly connected between the outlet (9) of the pump and the coupling (6) for the valve of the tire; a piston (15) is mounted inside the cylinder (13) so that it can move in contrast with an elastic lamina (22) and is connected to a rack (18) which meshes with a rotatable sprocket (26) with which a radial protrusion (28), provided with a pointer (29) for indicating the pressure on a graduated scale (30), is rigidly associated. <IMAGE></p> |
