摘要:
The present disclosure relates to an arrangement for transferring fluid to a guide bar in a chain saw. A channel can extend from a chain saw body to the fastening arrangement of the guide bar. The channel can include a cavity through the entire channel, a first end of the cavity being connected to a feed channel provided in the chain saw body and a second end thereof to a counter channel provided in the fastening arrangement. The counter channel, in turn, is arranged to extend to the guide bar. The channel is thus arranged to guide fluid flowing in the feed channel provided in the chain saw body through the channel and further through the counter channel provided in the fastening arrangement to the guide bar.

A lubricating oil line of a gas turbine or a turbocharger includes a flow path component which allows passage of a lubricating oil. The flow path component used in the gas turbine includes a sump chamber (45) and a vent line (49). A surface of the flow path component, which is exposed to a temperature approximately from 300 to 450°C and comes into contact with the lubricating oil, is covered with a coating that includes nickel or a nickel-phosphorus alloy, and particles made of polytetrafluoroethylene.

A motor control system for a lubricant pump motor comprises a pump system power input, a motor drive, a current sensor, a lubrication controller, and a drive controller. The pump system power input is configured to supply system power. The motor drive is configured to drive the lubricant pump motor using the system power. The current sensor is disposed between the pump system power input and the motor drive to sense an input current of the system power. The lubrication controller configured to provide motor activation signals. The drive controller is disposed to receive the motor activation signals via an isolated digital input, and to control the motor drive as a function of the sensed input current and a user-defined current set-point, in response to the activation signals.

An internal combustion engine (E) comprises a breather chamber (40) for performing gas liquid separation of blow-by gas produced within an engine main body (21), being formed on the inside of a head cover (26) which is connected to a cylinder head (25)in such a way as to hold a gasket (48) between itself and the cylinder head (25). An outlet pipe (39) is provided in the head cover (26) so as to lead out the blow-by gas from the breather chamber (40), and a hose (41) leads the blow-by gas to an air cleaner (29) side having an end portion joined to the outlet pipe (39). The influence upon the surrounding environment is suppressed at a lower level by releasing a pressure from a predetermined part on purpose, even if an internal pressure within the engine main body (21) is increased by blow-by gas. A release device (43) is provided in the outlet pipe (39) in order for releasing blow-by gas outwardly by separating a hose (41) from the outlet pipe (39) when the pressure of the blow-by gas within an engine main body (21) is not less than a predetermined pressure.

A connecting device (12) for the fluid-tight connection of a first and a second duct (2, 11) provided with a connector (14) having a fixed electrical connection terminal (15); a mobile electrical connector (18) for establishing an electrical connection with the fixed electrical connection terminal (15); a control unit (13) suited to check the presence of a connection between the fixed electrical connection terminal (15) and the mobile electrical connector; and an intermediate connecting body (17) interposed in use between the connector (14) and the mobile electrical connector (18), suited to establish an electrical connection between the fixed electrical connection terminal (15) and the mobile electrical connector (18) and suited to allow the fixed electrical connection terminal (15) and the mobile electrical connector (18) to be coupled to each other, only when there is a fluid-tight joint between the two ducts (2, 11).
摘要:
A series progressive divider valve comprises a valve body and pistons. The valve body comprises a fluid inlet, piston bores, outlet bores, porting and undercuts. The fluid inlet extends into an exterior of the valve body. The piston bores extend through the valve body from a first end to a second end. Each piston bores includes a piston. The outlet bores extend into the valve body, each outlet bores comprises a first set of outlet bores and a second set of outlet bores. The porting forms a plurality passageways connecting the piston bores to each other and with the outlet bores such that when high pressure fluid is applied to the inlet each of the pistons reciprocates from the first end to the second end in sequence. An undercut is located at an intersection between each passageway and piston bore.
