Abstract
A hydraulic coupler half simple enough for use in miniature couplings is disclosed. Both the relief ports and the main fluid ports are in the pintle. The relief ports are uncovered by a hyperextension of the pintle; the main fluid ports are uncovered by retraction of a sliding sleeve around the pintle. The pintle has a single annular contact point with the coupler body and clearances between the walls so that exact alignment is not necessary for connection. The nipple half is conventional.
