Retrofittable no filter no run filtration system
A retrofit no filter no run insert for existing filtration systems manufactured without a no filter no run engine integrity protection feature. The insert is beneficial for a manufacturer that initially does not require the benefit of a no filter no run engine integrity protection feature but later requires such a feature. The insert can be installed into the existing filtration system without any modification to the existing filtration system head. The no filter no run insert prevents the equipment supplied by the filtration system (e.g., an internal combustion engine) from being operated without a filter element. Further, the no filter no run insert prevents the equipment supplied by the filtration system from being operated with an unauthorized or non-genuine replacement filter element. The no filter no run insert safeguards against damage to downstream components of the filtration system and malfunctions of equipment in which the filtration system is used.
1. A method of converting a filtration system to no filter no run filtration system, the method comprising:
providing a filtration system that does not include a no filter no run feature;
providing a no filter no run insert having a cutoff valve; and
inserting the no filter no run insert into a fluid passageway of a mounting head of the filtration system.
2. The method of claim 1 , further comprising installing a filter element in the filtration system, the filter element including a no filter no run interaction mechanism.
3. The method of claim 2 , wherein installing the filter element comprises passing a valve interaction pin into the no filter no run insert between a ball and a fluid passage at an outlet of the no filter no run insert so as to substantially prevent the ball from engaging the fluid passage.
4. The method of claim 1 , wherein inserting the no filter no run insert into the fluid passageway comprises inserting the no filter no run insert into one of a fluid inlet or a fluid outlet of the mounting head.
5. The method of claim 1 , wherein inserting the no filter no run insert into the fluid passageway comprises forming at least one of a snap fit or a friction fit connection between a cage housing of the no filter no run insert and the fluid passageway.
6. The method of claim 1 , wherein providing the no filter no run insert comprises:
providing a cage housing;
providing the cutoff valve, the cutoff valve comprising a ball and a fluid passage, the ball sized such that the ball cannot pass through the fluid passage; and
engaging the cutoff valve with the cage housing.
7. The method of claim 6 , wherein engaging the cutoff valve with the cage housing comprises inserting the ball into the cage housing between the fluid passage and an inlet of the cage housing upstream of the fluid passage such that the ball is retained between the fluid passage and the inlet.
8. The method of claim 1 , wherein inserting the no filter no run insert into the fluid passageway comprises aligning an alignment rib with a slot in the mounting head, the alignment rib extending parallel to a central axis of a cage housing of the no filter no run insert.
9. The method of claim 1 , wherein inserting the no filter no run insert into the fluid passageway comprises engaging a cage of the no filter no run insert with the fluid passageway so that an outward facing surface of the cage sits flush with surrounding surfaces of the mounting head.
10. The method of claim 1 , wherein inserting the no filter no run insert into the fluid passageway comprises engaging a cage of the no filter no run insert with the fluid passageway so that the cage seals against the mounting head via a plastic to metal interference seal.
11. The method of claim 1 , wherein the cutoff valve includes a ball having a ball diameter and a fluid passage having a fluid passage diameter, the ball diameter being greater than the fluid passage diameter such that the ball will block the fluid passage as a fluid being filtered by the filtration system carries the ball into the fluid passage unless a filter element having a valve interaction pin is used within the filtration system.
