Liquid dispensing device

A liquid dispensing device (10) including a body (12) generally having an air passage (24) and a liquid passage (22). A valve seat element (14) is connected to the body (12) and a needle (16) is mounted for movement within the body with respect to the valve seat element (14). First and second connected needle guides (18,20) receive respective portions of the needle (16) in a manner inhibiting sideward movement thereof. The first needle guide (18) allows flow of liquid through the liquid passage adjacent the first needle guide (18) to the dispensing orifice (25) when the needle (16) is moved away from the valve seat (14). The first needle guide (18) is connected to the valve seat (14) by way of a press fit and is connected to a second needle guide (20) by way of another press fit. The connected needle guides (18,20) are likewise press fit into a bore in the body (12). These connections all aid in maintaining close tolerances and excellent alignment of the needle (16). A liquid seal is generally disposed between the first (18) and second (20) needle guides and prevents liquid from entering the air passage (24). The needle (16) may be moved by pressurized air acting against a piston (60) and the needle (16) may be normally closed by a spring return mechanism (90) when the pressurized air has been shut off. A pivotal force transfer element associated with the spring return mechanism reduces side load on the needle.
