Embodiment Construction

[0017] refer to figure 1 , the device of the present invention comprises a housing 10 which is mainly molded from plastic except for the exposed metal strip which is the outer edge of the metal strip casing 11, as image 3 shown in the cross-section. The housing 10 ( figure 1 ) includes: a head 12; a circular handle 13 extending from the head 12; and a trigger guard portion 15 extending from the head 12 and connecting to the remote connection. The device includes a trigger 14, which is a metal operating rod, which, when pressed against the handle 13, will further operate a valve (not shown) for opening and closing to control the flow of liquid. Liquid enters through inlet hole 16 and exits through outlet hole 17 . The chevrons or protrusions 13a are spaced along the handle 13 for better grip.

[0018] The device also includes a bezel portion 18 which fits around a visual display 19, and a set of six programming keys 20 and a mechanical button 21 which will be described in...

Abstract

A device for delivering a preset volume of fluid, such as oil, includes a casing (10) with an inlet port (16), an outlet port (17) and supply passages (22, 24) for flow of fluid from the inlet port (16) to the outlet port (17). A valve including a valve member (24) is situated to control the flow of the fluid through a valve chamber (23). The valve is manually actuated to an open position and held by momentary energization of a latching solenoid (36). When the fluid volume reaches a preset volume, the latching solenoid (36) is energized again to allow the release the valve member (24) to return to a closed position. In the event of a battery low condition, the latching solenoid (36) can be disabled, so that the valve can only be held open manually, thereby preventing an electrical failure with the valve open. A manual push button (21) is directly connected to the valve member (24) for closing the valve manually. A method for controlling the dispensing of a fluid is also disclosed.

Description

technical field [0001] The present invention relates to a metering gun or nozzle for dispensing lubricating fluid. Background technique [0002] In the vehicle service field, hand-held metering guns or nozzles are used to dispense predetermined quantities of lubricating fluid, such as oil. The device has an operating lever that can be pressed against the handle to start work. The metering portion of the device then measures the amount of fluid passing through the device and closes the valve when a predetermined amount of fluid has been dispensed. This device is useful in vehicle service where oil or other lubricants are supplied in large quantities. The device also has other industrial uses. [0003] In the prior art, such devices employ mechanical metering mechanisms. These mechanisms have many parts that are prone to wear and tear. [0004] Electronic control makes manufacturing cheaper, but in order to obtain these advantages, certain problems in converting to electr...
