Abstract: A liquid dispensing system equipped with a modular cord set for powering an electrically-operated dispensing module of the system. The cord set includes a plug removably inserted into receptacle extending through a manifold of the system. The manifold heats and supplies liquid to the dispensing module. When the plug is positioned in the receptacle, electrical contacts on the plug are coupled with corresponding electrical contacts on the dispensing module. The cord set and dispensing module can be independently disconnected from the manifold without disturbing each other.

Abstract: A device for dispensing a heated liquid, such as a hot melt adhesive, which includes a heated dispenser body having a liquid passage in communication with a liquid inlet and a liquid outlet. The dispenser body further includes a valve element having a circumferential groove therearound cooperating with a recessed portion of the dispenser body to define a cavity about the valve element. A flexible seal is situated within the cavity between the liquid passage containing the heated liquid and an upper area of the dispenser body. A first portion of the seal is configured to form a fluid tight seal within the recessed portion and a second portion is configured to form a fluid tight seal about the valve element during reciprocation thereof relative to the recessed portion, thereby preventing liquid from leaking out of the liquid passage past the flexible seal and into the upper area.

Abstract: A locking hydraulic fitting for establishing a fluid connection with a fluid manifold, such as a manifold of a dispensing apparatus. The hydraulic fitting includes a body with a threaded portion capable of being engaged with a threaded inlet or another threaded portion of the manifold. The body of the hydraulic fitting hydraulically couples a fluid channel of the manifold with a fluid supply conduit. The hydraulic fitting includes a lock member configured to prevent rotation of the threaded portion of the hydraulic fitting relative to the threaded inlet or other threaded portion of the manifold.

Abstract: A hydraulic swivel fitting for establishing a fluid connection with a liquid dispenser. The swivel fitting includes a fluid cavity housing a socket assembly, a ball member that rotates and tilts within the socket assembly, and a stem that is received within a bore in the ball member with a liquid-tight seal. The stem is movable within the bore so that axial forces applied to a supply conduit coupled with the stem are not transferred to the ball member. Instead, such axial forces are diverted from the stem to the housing of the swivel member and, subsequently, transferred from the housing to the liquid dispenser.
