Abstract
Disclosed herein is a nozzle assembly comprising a housing including a central bore having, at one end thereof, a valve seat, an elongated needle member having, at one end thereof, a valve portion engageable with the valve seat, and having, at the other end thereof, an end portion, a retainer member having therein a bore receiving the end portion of the needle, and being fixed to the end portion of the needle, and a spring acting between the housing and the retainer member to bias the valve portion into engagement with the valve seat, and a method of assembly therefor comprising the steps of locating the needle member in the bore in the housing with the valve portion in engagement with the valve seat and with the end portion extending from the housing, locating the spring in surrounding relation to the end portion of the needle member and in operative engagement with the housing, locating the retainer member with the end portion of the needle member passing through the bore in the retainer member, spacing the retainer member from the housing with the spring in compression between the retainer member and the housing, fixing the retainer member to the end portion while maintaining the spacing of the retainer from the housing and while maintaining the engagement of the valve portion of the needle member with the valve seat and with the spring in compression between the housing and the retainer member, and removing the spacing from between the housing and the retainer member, thereby permitting movement of the valve portion of the needle member away from the valve seat in opposition to action of the spring.
