Embodiment Construction

[0024] Detailed description of the preferred embodiment

[0025] Referring to the accompanying drawings, the improved grease connector device is described in detail.

[0026] figure 1 The general structural layout of a conventional grease supply system is shown. The system features a grease gun (1) that delivers pressurized grease through a delivery line (2) via a grease connector (3). The grease connector (3) mates with the zerk fitting (4) secured to the bearing / hub (5). This connector forms a leak-proof seal with the filler nipple fitting. This arrangement shows only a manually operated manual grease gun with a hose. However, there are many grease dispensing units that can take advantage of the common benefits of this modified connector when connected to a standard grease fitting.

[0027] figure 2 A preferred embodiment of the invention is shown. The figure shows an elongated body (10) in which a channel (11) is opened throughout its entire length. An inlet (12) i...

Abstract

An improved grease coupler 3 allows for positive, coupling and uncoupling from a grease nipple 4 via a manually operated trigger mechanism 30. The coupler includes a replaceable seal 13 and comprises an elongate body 10 with a grease passage 11 through the length of the body. A floating barrel plunger 42 acts as a check valve to prevent grease leaking from the discharge end of the elongate body 10 upon disconnection.

Description

[0001] Technical Field of the Invention [0002] The present invention relates to an improved device for connecting the pressurized nozzle of a grease gun to a standard Zerk type nozzle. Background technique [0003] Conventional Zerk connectors (Zerk couplers) and Zerk nipples (Zerk nipples) have remained largely unchanged for more than fifty years. Although there are other types of connectors and grease nipples on the market, only the Zerk type has come close to being an international standard. [0004] When a standard Zerk-style connector is connected to a mating grease nipple, the connector pushes against the nipple. This push causes the clamping jaws to move back against spring tension into a tapered cavity, allowing the grip The pliers are spread open over the head of the grease fitting. When this manual force is released, the internal spring will drive the clamping jaws forward to form a tapered cavity and thus clamp the clamping jaws on the head of the nozzle. The a...
