Abstract (en)
A pop-up sprinkler device (3) is described comprising an external housing (4) and an internal mobile part (5) that is provided with a delivery head (9), that partially comes out of the external housing (4) when it is supplied with water in pressure that is coming from a supply pipe below (1). The lower end of said internal mobile part (5) is provided with a valve (14) that closes the water inlet once the pressure of supply of the same water stops. The valve (14) has small slots (16) that are suitable to allow, in the absence of pressure, the drainage of the water toward said pipe below (1). <IMAGE>
