COOLER BYPASS APPARATUS AND INSTALLATION KIT
First Claim
1. A bypass valve adapted to be fluidically coupled between a heat exchanger and a device carrying fluid that needs to be cooled, the bypass valve comprising:
- a housing having an inlet port and first and second outlet ports in fluid flow communication with a fluid flow passageway in the housing; and
temperature responsive means, disposed in the housing, for opening and closing the first and second outlet ports to fluid flow from the inlet port in response to the temperature of fluid flowing in the passageway in the housing.

Abstract
A cooler bypass valve apparatus installed the apparatus between a heat exchanger and conduits coupled to a device carrying fluid that needs to be cooled. A housing includes an inlet port and first and second outlet ports. At least one thermal actuator and at least one valve are mounted in a fluid flow passageway in the housing and operative in response to the fluid temperature to move the at least one valve between operative positions opening and closing fluid flow from the inlet port through the first and second outlet ports between a heat exchanger bypass loop and a heat exchanger cooling loop. In another aspect, two thermal actuators control a separate valve associated with the first and second outlets between open and closed positions enabling fluid flow from the inlet port exclusively through one of the first and second outlet ports or in a combined partial flow through both of the first and second outlet ports.

39. A method of installing a cooler bypass apparatus to a heat exchanger carrying coolant fluid coupled by first and second conduits to a device with fluid that needs to be cooled, the method comprising the steps of:
-
providing a first body having a first inlet adapted to be fluidically coupled by a first connection to the first conduit, providing a first outlet, and a quick connector coupled to the first inlet; providing a second outlet adapted to be coupled by a third connection to the heat exchanger inlet; fluidically connecting the first outlet of the first body to the first inlet of the second body by a second fluidic connection; fluidically coupling a thermal actuator in the bore in the first body for normally blocking fluid flow between the first inlet and the second outlet of the first body at fluid temperatures below a preset temperature and unblocking fluid flow between the first inlet and the second outlet of the first body at fluid temperatures above a preset temperature; and fluidically coupling a check valve to the first outlet in the first body for blocking flow from the first outlet through the second connection when fluid pressure is less than a normal biasing force exerted on the check valve and allowing flow from the first outlet through the second connection when the fluid pressure is greater than the biasing force acting on the check valve. - View Dependent Claims (40)
