An oil change cap and system are described. A removable oil cap kit includes a removable oil cap and an oil retention bag. The removable oil cap incudes a sidewall and an interior surface, the interior surface has an opening extending therethrough. The sidewall includes an inner portion and an outer portion. The outer portion of the sidewall includes a channel formed therein for retaining an oil retention bag. The inner portion of the sidewall includes one or more protrusions to couple the removable oil cap with the oil receptacle of a motor.

A machine for replacing used transmission or power steering fluid in a vehicle with new transmission or power steering fluid includes a frame having a housing. The machine includes a pair of service hoses that extend from the machine and connect to the vehicle for placing the machine in the fluid flow. New, used, and axillary fluid tanks are provided. A pump and a manifold are associated with two of the tanks. The pumps provide for the selective withdraw or insertion of fluid into or out of the tanks. A display on the housing presents an operator of the machine with various tasks or options the machine can perform. A processor controls activation of the pumps and other electrical components based on inputs received by the display. Scales are provided under one or more of the tanks for determining the amount of fluid going into and out of the tanks during the exchange process.

A service tool is designed for releasable coupling to a service port receiver connected to a service port associated with a gearbox. The service tool includes a coupling arrangement for releasably coupling to the service port receiver. The coupling arrangement is configured for rotational movement about the said receiver between a released position and an engaged position. A locking actuator is operatively coupled to the coupling arrangement and arranged for axial movement between a locked position and an unlocked position relative to the service port receiver. A plunger actuator is adapted for connection to the fluid conduit, which plunger actuator is slidably coupled to the coupling arrangement for movement between open and closed positions. In the open position, with the coupling arrangement in the engaged position and the locking actuator in the locked position, the plunger actuator is adapted to contact a check valve of the service port receiver and open it to permit fluid flow between the gearbox and the fluid conduit via a fluid pathway formed at least in part by the plunger actuator.

Embodiments of the invention provide a liquid fill kit system including a rollable cart having a frame and a plurality of wheels. A tank disposed within the frame. The fill kit further includes a fluid pump including a suction interface connection and a discharge interface connection. A filter assembly mounted within the frame. A fluid pressure regulator include a fluid outlet port, the fluid pressure regulator being configured to stop a flow of fluid when a pressure exceeds a fluid pressure threshold. In a first configuration, the suction interface connection is in fluid communication with the tank, and the discharge interface connection is in fluid communication with the filter unit, the pressure regulator, and the fluid outlet port to generate a flow of fluid through the fluid outlet port.

A system. The system includes a valve assembly. The valve assembly includes a first port, a second port fluidically couplable with the first port upon application of negative pressure at the first port, a third port fluidically couplable with the first port upon application of positive pressure at the first port, and a first check valve positioned between the first port and the second port. The system also includes a second check valve fluidically couplable with the third port upon the application of the positive pressure at the first port. The second check valve is positioned external to the valve assembly.

A device for reciprocatingly removing and replenishing fluid in circulating system of an hydraulic mechanism that includes at least two processing tanks, at least one air pressure regulator and connector releasably engageable with a pressurized air source, at least one vacuum generator, at least one pressure regulator; and means for removing the fluid from the circulating system at vacuum.

A drain tool assembly adapted to couple to a housing without causing fluid to flow from the housing until moved to a draining position. The drain tool assembly avoids fluid spillage by sealing a body to the housing and then engaging a plunger of the housing by moving and locking a sleeve to initiate a flow of fluid from the housing.

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.

In order to fill a reservoir while avoiding laborious manual filling operations, there is added to the existing device, including a supply duct, a pump and a measuring probe, a stop valve designed to interrupt the filling as soon as the desired level has been reached, which is detected for example by an air intake which controls the closure of the valve. Two level indicators are added and make it possible to ascertain either that optimum filling has been achieved or that a malfunction is present in the system. Application to the systems for oil filling of aircraft engine reservoirs from another reservoir arranged within the aircraft, generally common to all the engines.

A gas turbine engine for an aircraft comprises: an engine core comprising a turbine, a compressor, and a core shaft connecting the turbine to the compressor. The gas turbine engine further comprises a core casing surrounding the engine core. The gas turbine engine further comprises a core cowl surrounding the engine core and the core casing. The gas turbine engine further comprises an engine accessory gearbox driven by a take-off from the core shaft. The gas turbine engine further comprises an oil system having one or more oil pumps powered by the engine accessory gearbox for circulating lubricating oil around components of the engine including the engine accessory gearbox, and having an oil tank for receiving and storing oil scavenged from the engine components before recirculation thereto. The gas turbine engine further comprises an oil fill line which extends from the engine accessory gearbox to an inlet port accessible from the core cowl, the oil tank being fillable from the inlet port via the fill line and the engine accessory gearbox.
