Abstract
A packaged delivery for short term lubrication including dispenser assembly, flow control assembly, pressure supply assembly and releasing mechanism assembly. Dispenser assembly includes a dispenser filled with oil. Dispensers can be placed within a shaft, a bearing house and a strut. Pressure supply assembly provides pressure to the oil stored in the dispenser. In one embodiment pressure supply is a mechanical pressure source. In an alternative embodiment, the pressure is a compressed gas. In one embodiment, the releasing mechanism assembly includes a thermal rupture mechanism. In another embodiment, the releasing mechanism assembly includes a mechanical rupture mechanism. Flow control assembly includes analog and digital controls to control flow rate of oil.
Claims20
A packaged oil delivery for short term lubrication, comprising:
- A) a working zone assembly including a strut, a bearing housing and a shaft;
- B) a dispenser assembly including a dispenser, a reservoir and a valve, said dispenser is located in the strut to provide oil to said bearing housing, said reservoir is enclosed by the dispenser, said reservoir storing oil, said valve communicates reservoir with exterior of the dispenser to dispense said oil;
- C) a control assembly located at the valve of the dispenser assembly controlling a flow rate of the oil flowing through said valve;
- and
- D) a releasing mechanism assembly including a mechanical rupture mechanism, a thermal rupture mechanism and a non-rupture mechanism, wherein the mechanical rupture mechanism or the thermal rupture mechanism is located at an outlet of said valve.

A packaged oil delivery for short term lubrication, comprising:
- A) a working zone assembly including a strut, a bearing housing and a shaft;
- B) a dispenser assembly including a dispenser, a reservoir and a valve, said dispenser is located in the strut to provide oil to said bearing housing, said reservoir is enclosed by the dispenser, said reservoir storing oil, said valve communicates reservoir with exterior of the dispenser to dispense said oil, wherein the dispenser includes an inlet and a gas reservoir, wherein said gas reservoir is located within the reservoir and the inlet, wherein the dispenser assembly further includes a threaded portion to removably attach the dispenser to the working zone assembly;
- C) a control assembly located at the valve of the dispenser assembly controlling a flow rate of the oil flowing through said valve, wherein the control assembly includes an active analog valve to control the flow rate of the oil flowing through the valve, wherein the active analog valve is configured to be actuated based on operating conditions of the working zone assembly;
- D) a releasing mechanism assembly including a mechanical rupture mechanism, a thermal rupture mechanism and a non-rupture mechanism, wherein the mechanical rupture mechanism or the thermal rupture mechanism is located at an outlet of said valve;
- and
- E) a pressure supply assembly contained within said dispenser, wherein the pressure supply assembly increases pressure of the oil stored in the reservoir, wherein the pressure supply assembly includes a compressed gas to supply pressure to the oil contained in the reservoir, wherein the compressed gas is stored in said gas reservoir, said inlet allows to fill said gas reservoir with said compressed gas.

- A) a working zone assembly including a strut, a bearing housing and a shaft;
- B) a dispenser assembly including a dispenser, a reservoir and a valve, said dispenser is located in the strut to provide oil to said bearing housing, said reservoir is enclosed by the dispenser, said reservoir storing oil, said valve communicates reservoir with exterior of the dispenser to dispense said oil, wherein the dispenser assembly further includes a threaded portion to removably attach the dispenser to the working zone assembly;
- C) a control assembly located at the valve of the dispenser assembly controlling a flow rate of the oil flowing through said valve, wherein the control assembly includes a controller, a proportional flow valve, thermistor and a flow meter, wherein the thermistor sets a desired flow rate of said oil to the controller, wherein said flow meter provides a feedback to the controller, said controller driving said proportional flow valve to regulate the flow rate of said oil, wherein the controller is an analogical controller;
- D) a releasing mechanism assembly including a solenoid valve, wherein said solenoid valve is located at an outlet of said solenoid valve is driven by said thermistor to release said oil;
- and
- E) a pressure supply assembly contained within said dispenser, wherein the pressure supply assembly increases pressure of the oil stored in the reservoir, wherein said pressure supply assembly includes a spring and a plunger enclosed inside reservoir, a first end of the spring is attached to a top reservoir end, a second end of the spring is attached to the plunger, said spring produces a constant force along the reservoir to produce a pressure to the oil stored in said reservoir.
