A valve system is disclosed herein. The valve system, in one arrangement, may comprise: a fluid pathway for transporting a fluid; a first valve operably coupled to the fluid pathway, the first valve comprising a first resilient element; a second valve operably coupled to the fluid pathway, the second valve comprising a second resilient element that is substantially identical to the first resilient element; wherein, when the first valve is in a closed state, the first resilient element is compressed to a first length so that the first valve opens at a first pressure; and wherein, when the second salve is in a closed state, the second resilient element is compressed to a second length so that the second valve opens at a second pressure, the first length is less than the second length such that the second pressure is less than the first pressure.

A lubrication system for an internal combustion engine. The lubrication system may comprise an oil cooler; an oil cooler supply passage for delivering oil to an inlet of the oil cooler from an oil reservoir; an oil cooler outlet passage for delivering oil from an outlet of the oil cooler to one or more portions of the internal combustion engine to be lubricated; a first pressure relief valve operably coupled to the oil cooler supply passage, the first pressure relief valve configured to open at a first predetermined pressure to allow oil in the oil cooler supply passage to return to the oil reservoir without passing through the oil cooler; and a second pressure relief valve operably coupled to the oil cooler outlet passage, the second pressure relief valve configured to open at a second predetermined pressure to allow oil in the oil cooler outlet passage to return to the oil reservoir after passing through the oil cooler, the second predetermined pressure being less than the first predetermined pressure.

A gasoline powered engine configured to operate in a substantially horizontal orientation and to be stored in a generally vertical orientation without leaking of fluid contained in the gasoline powered engine may include an oil sump and a first oil drain port extending in a first direction through a first wall of the sump. The first wall forms a bottom of the sump when the engine is in the vertical orientation.

A power transmission device includes: a case including a first oil reservoir configured to store oil, a second oil reservoir configured to store the oil, and a partition wall configured to separate the first oil reservoir and the second oil reservoir from each other; the oil enclosed in the case; a rotating member configured to contact the oil in the first oil reservoir; and an opening and closing member located in the partition wall and configured to supply the oil from the second oil reservoir to the first oil reservoir. The oil level in the first oil reservoir when the opening and closing member is open is higher than the oil level in the first oil reservoir when the opening and closing member is closed, and is high enough for at least a part of the rotating member to be dipped in the oil.

An oil sump for supplying an assembly of a motor vehicle, including: a housing including a housing frame and a closure part, such as for example a housing cover, which is joined to the housing frame; an oil accommodating space enclosed by the housing. The housing frame circumferentially surrounds the oil accommodating space; and a suction channel which extends into the oil accommodating space and includes an opening via which oil can be delivered or suctioned from the oil accommodating space through the suction channel. The suction channel is formed by the housing frame and the closure part.

A lubricant pan for a vehicle includes a receiving region in which a lubricant is at least temporarily receivable, a first wall element, and a second wall element. A temperature-control channel is disposed between the first wall element and the second wall element and a temperature-control medium is flowable through the temperature-control channel. A core that is porous and permeable to the temperature-control medium is disposed in the temperature-control channel between the first wall element and the second wall element. The temperature-control medium is introducible into the temperature-control channel via a first connector and the temperature-control medium is dischargable from the temperature-control channel via a second connector.
