Definitions

  • the present invention relates to the cooling of lubricating oil in a motorcycle engine. More particularly, the present invention relates to oil cooler bypass valve assemblies of the type utilizing a thermally responsive element to effect valve actuation.
  • An internal combustion engine as commonly used to propel a motorcycle, generates a great deal of heat as a product of the cumulative combustion events and friction. Lubrication of the engine can become a challenge when the oil that provides the lubrication becomes overheated and loses some of its characteristic viscosity.
  • a valve assembly such as the one disclosed in U.S. Patent No. 4,190,198 (Casuga et al.), can be used to divert the oil to the oil cooler only when the oil needs to be cooled.
  • This valve assembly provides a temperature sensitive mechanism that operates in a first position when the oil is below a threshold temperature, and moves to a second position when the oil reaches the threshold temperature.
  • valve assembly In the second position, the valve assembly diverts the oil flow to the oil cooler and provides a return path from, the cooler to the engine.
  • the valve assembly occupies additional space in the engine compartment, and requires additional wiring and hoses when added as an aftermarket feature to the engine.
  • the present invention provides a temperature-sensitive valve assembly that is incorporated into an oil filter assembly and is configured to divert oil to an oil cooler when the oil in the filter assembly reaches a certain temperature. Because the valve assembly is contained within the oil filter assembly, no additional engine compartment space is needed to accommodate the valve assembly. Also, positioning the valve assembly in the oil filter assembly reduces the number of separate parts attached to the motorcycle, provides protection to the valve assembly, and improves the aesthetics of the motorcycle.
  • the present invention provides an oil filter assembly comprising a housing including an inlet port for receiving oil from the engine, an outlet port for returning oil to the engine, and a bypass passage adapted to be connected to an oil cooler.
  • An oil filter is secured to the housing to complete a main oil path between the inlet port and the outlet port.
  • a temperature-sensitive valve assembly is located within the main oil path and movable from a cold position to a hot position. The valve assembly is oriented to bypass oil from the main oil path to the bypass passage when in the hot position.
  • the filter assembly further includes a return passage in communication with the main oil path and adapted to return oil from the oil cooler to the housing.
  • the housing further includes a cavity interconnecting the inlet port with the outlet port and at least partially defining the main oil path.
  • the valve assembly is located within the cavity and is movable between the hot position and the cold position in a direction substantially parallel to an outlet axis defined by the direction oil travels when passing through the outlet port.
  • the movement of the valve assembly is also substantially parallel to an inlet axis defined by the direction oil travels when passing through the inlet port. It is also desirable to position the oil filter such that oil entering the oil filter flows along a filter axis that is substantially perpendicular to the outlet axis.
  • Fig. 1 illustrates a motorcycle 20 having a front wheel, a frame 24 supported by the front wheel 22, and engine 26 supported by the frame 24, an oil filter assembly 28 that filters engine oil, and an oil cooler 30 that cools engine oil.
  • the oil filter assembly 28 and the oil cooler 30 are interconnected with a pair of oil conduits 32. It should be appreciated that, although the oil filter assembly is illustrated mounted to the front of the engine 26, the oil filter assembly 28 could be mounted in any appropriate location on the motorcycle 20.
  • the oil filter assembly 28 generally includes a housing 34 adapted to be mounted to a motorcycle 20, and a temperature-sensitive valve assembly positioned within the housing 34 and adapted to divert oil to the oil cooler 30 when necessary.
  • the housing 34 is designed to interconnect with an oil filter 38 having a filter element 40.
  • the housing 34 includes a base portion 42 having multiple openings 44 designed to receive fasteners 46 to facilitate securing the housing 34 to the engine 26.
  • the housing 34 further includes a filter portion 48 designed to support the oil filter, and a body portion 50 interconnecting the base portion 42 with the filter portion 48.
  • a series of passages directs oil through the housing 34.
  • An inlet port 52 received oil from the motorcycle 20 and an inlet passage 54 directs the oil to the oil filter (Figs. 6, 8, 10, and 12). More specifically, the inlet passage extends from the inlet port 52 to a filter entrance passage 56, which leads to the entrance side of the filter element.
  • the inlet passage 54 includes an irregular-shaped portion 58 to prevent the inlet passage 54 from intersecting other passages. In the illustrated embodiment, the irregular-shaped portion 58 is D-shaped.
  • a filter exit passage 60 provides communication between the exit side of the filter element 40 and a primary cavity 62 (Figs. 4, 8-11, 13, and 14).
  • the primary cavity 62 is partially defined by a primary plug 64 that is threaded into the housing 34.
  • a primary gasket 66 provides a seal.
  • the primary cavity 62 provides a location for the valve assembly 36.
  • a bypass passage 68 provides a pathway from the primary cavity to a bypass fitting 70 (Figs. 2, 7-9, 11, 13, and 14) that is adapted to be connected to one of the conduits 32 (Fig. 1).
  • the bypass passage 68 bypasses oil to the oil cooler 30, as described below.
  • a return passage 72 provides a pathway from a return fitting 74 back to the primary cavity 62 (Figs. 2, 7-10, 13, and 14).
  • the return passage 72 returns oil from the oil cooler 30 to the primary cavity 62, as described below.
  • the bypass passage 68, conduits 32, oil cooler 30, and return passage 72 are collectively referred to as the bypass circuit.
  • the housing 34 further includes a secondary passage 76 and secondary cavity 78 (Figs. 2, 3, 9, 13, and 14) that allow oil to travel past the valve assembly 36 under certain conditions, as described below.
  • the secondary cavity 78 is partially defined by a secondary cap 80 that is secured to the housing 34 by fasteners 82 and washers 84.
  • a secondary gasket 86 provides a seal.
  • An outlet passage 88 provides communication from the primary cavity 62 to an outlet port 90, which is in communication with the engine 26 (Figs. 1, 4, 6, 8, 9, and 11-14).
  • the path that the oil follows between the inlet port 52 and the outlet port 90 is referred to as the main oil path.
  • the valve assembly 36 includes a thermostat 92 having a main portion 94 and a plunger 96 that is movable relative to the main portion 94 (Figs. 2, 13, and 14).
  • the position of the plunger 96 relative to the main portion 94 is dependent on the temperature of the thermostat 92, which is dependent on the temperature of the oil surrounding the main portion 94 of the thermostat 92.
  • the illustrated thermostat 92 is a hot wax thermostat that is commercially available, from Caltherm of Bingham Farms, Michigan.
  • the plunger 96 of the thermostat 92 is engaged with a spacer 98 having a central support portion 100 and several leg portions 102 (Figs. 2, 13, and 14).
  • the spacer 98 provides support to the plunger 96 and spaces the plunger 96 away from the outlet port 90 so that oil can flow around the plunger 96 and to the outlet port 90. Because the plunger 96 is, in essence, held in place by the spacer 98, movement of the plunger 96 relative to the main portion 94 (i.e., corresponding with a change in temperature of the oil in the housing 34) will result in movement of the main portion 94.
  • a valve member 104 is engaged with and moves with the main portion 94 (Figs. 2, 13, and 14).
  • the valve member is designed to move between a cold position that blocks the bypass circuit (Fig. 13) and a hot position that blocks the main circuit (Fig. 14).
  • the bypass circuit When in the cold position, the bypass circuit is blocked by blocking the return passage 72.
  • the main circuit When in the hot position, the main circuit is blocked by blocking the secondary passage 76.
  • a spring 106 biases the valve member 104 and thermostat 92 toward the outlet passage 88 to maintain contact between the plunger 96 and the spacer 98.
  • bypass circuit is used as a relative term, and is not meant to require complete obstruction.
  • bypass circuit when it is stated that the bypass circuit is blocked, it is intended to mean that the bypass circuit is obstructed to a greater extent when the valve assembly 36 is cold compared to when the valve assembly is hot.
  • oil when it is stated that oil is "bypassed”, it is intended to mean that a larger amount of oil passes through the bypass circuit when the valve assembly 36 is hot compared to when the valve assembly 36 is cold.
  • oil from the engine 26 enters through the inlet port 52 and travels through the inlet passage 54 and filter entrance passage 56 to the filter element 40. After being filtered, the oil passes through the filter exit passage 60 and into the primary cavity 62. At this point, the path of the oil is dependent on the position of the valve assembly. If the temperature of the oil is relatively low, the valve assembly 36 will be in a cold position with the valve member 104 blocking the return passage 72 (Fig. 13). In this configuration, the oil will pass through the secondary passage 76, into the secondary cavity 78, and back to the primary cavity 62, where the oil will exit through the outlet passage 88, the outlet port 90, and back to the engine 26.
  • valve assembly 36 In contrast, if the temperature of the oil is relatively high, the valve assembly 36 will be in a hot position with the valve member 104 blocking the secondary passage 76 (Fig. 14). This forces the oil to travel from the primary cavity 62 to the bypass passage 68, which leads to the oil cooler 30. After being cooled, the oil passes through the return passage 72 and back to the primary cavity 62, where it will exit through the outlet passage 88, the outlet port 90, and back to the engine 26.
