The present invention is directed to an oil drip pan assembly easily affixed to the undercarriage of a vehicle that catches oil as it drips thereby preventing the oil from reaching the ground. The assembly includes an oil drip pan and an access panel. The access panel covers an access aperture in the oil pan which allows for access to the undercarriage of the vehicle for performance of oil changes without removal of the entire oil drip pan assembly. The access panel includes water weep holes and a selectively oil absorbent mat to expel water and retain oil.

A diffuser for an oil drainback system drain tube includes a flow chamber configured for attachment to an open end of a drain tube, wherein the flow chamber has a side wall and an end wall, and openings in at least the side wall.

An adjustable liquid containment device for use with refrigerators to prevent overflow and damage to flooring. The containment device allows for appliance elevation within an integral support and water collection pan. The detachable loading ramps provide for smoothly rolling the appliance up onto the integrated independent elevated level support surfaces within the water retainment pan. The containment device is telescopically adjustable to accommodate different size appliances.

An assembly is provided for an aircraft propulsion system. This assembly includes a first drain tube, a second drain tube, a container and a gas tube. The container fluidly couples the first drain tube to the second drain tube. The container is configured to receive fluid from the first drain tube. The gas tube is fluidly coupled with the container. The gas tube is configured to direct gas into the container for propelling the fluid received within the container into the second drain tube.

The present disclosure discloses an oil-retaining mechanism, a valve structure, and a water outflow device. The oil-retaining mechanism comprises a valve body, a valve shaft, and a sealing member. The valve body comprises a motion cavity. The valve shaft is disposed in the motion cavity and configured to move axially. The sealing member is disposed between a cavity wall of the motion cavity and the valve shaft. At least one of the cavity wall of the motion cavity, the sealing member, or a connection portion of the motion cavity, the sealing member, and the valve shaft extends inward to define an oil storage groove. The oil storage groove comprises an opening. An inner side of the opening stores lubricating oil. The opening cooperates with and contacts the outer circumferential surface of the valve shaft. When the valve shaft moves in the motion cavity, the lubricating oil lubricates the valve shaft.

A filling and draining device for filling lubricant into and draining lubricant out of a housing (1), having a lubricant line (2, 21, 22) through which the lubricant passes into the housing (1), during filling, and through which the lubricant passes when the lubricant is drained from the housing (1). The housing (1) has a valve (6) through which the lubricant flows during filling and draining such that, for filling, the valve (6) adopts a first aperture width for the lubricant and, for draining, the valve (6) adopts a second aperture width for the lubricant.

An environmental containment device includes a baseplate extending a longitudinal length and two ends disposed at opposing ends of the longitudinal length. The baseplate has two longitudinal edges extending along the longitudinal length and two lateral edges extending along a lateral width of the baseplate. A flexible sidewall can extend along at least a portion each of the lateral edges and vertically extend away from the baseplate a second predetermined distance. The baseplate flexible sidewall collectively define a containment space.

A collapsible containment berm having a floor and a peripheral sidewall, a plurality of brace assemblies integrally carried on an external surface of the sidewall and on an adjacent underside surface of the floor, each brace assembly comprising a rigid sidewall support member connected to the external surface of the sidewall and oriented upright when deployed, a rigid buttress member having a first end and an opposite second end, and hingedly connected to an upper end of the sidewall support member that allows the buttress member to arc toward or away from the sidewall, a rigid floor member hingedly connected at the third end to the other end of the buttress member, and a sleeve connected to the underside of the floor and adapted to receive the floor member. The floor member slides in and out of the sleeve and moves the buttress member in and out of a bracing position with respect to the sidewall.

A gyrostabiliser having a vacuum chamber assembly is disclosed. The gyrostabilizer can have a flywheel enclosed within a vacuum chamber formed by a housing. The flywheel shaft can be fixed to or integral with the flywheel and located relative to the housing by upper and lower spin bearings which permit rotation of the flywheel about the spin axis.
