Abstract: A liquid dispensing device including a body generally having an air passage and a liquid passage. A valve seat element is connected to the body and a needle is mounted for movement within the body with respect to the valve seat element. First and second connected needle guides receive respective portions of the needle in a manner inhibiting sideward movement thereof. The first needle guide allows flow of liquid through the liquid passage adjacent the first needle guide to the dispensing orifice when the needle is moved away from the valve seat. The first needle guide is connected to the valve seat by way of a press fit and is connected to a second needle guide by way of another press fit. The connected needle guides are likewise press fit into a bore in the body. These connections all aid in maintaining close tolerances and excellent alignment of the needle. A liquid seal is generally disposed between the first and second needle guides and prevents liquid from entering the air passage.
