Abstract:
A method and apparatus automatically feeds lubricating oil to machine parts using a microcomputer. According to the method and apparatus, the lubricating oil discharge time for each discharge mode is set and the operation of an electrochemical reactor is controlled in accordance with the set discharge mode under the control of the microcomputer. At the completion of the set discharge time, a discharge mode for a preset minimum period of discharge time, such as one month, is set to allow complete discharge of the remaining lubricating oil. The set discharge mode and the determined discharge time are displayed on a liquid crystal display for convenient viewing by a user.
Abstract:
A method for reconfiguring a jig for supporting an elongated workpiece to enable the jig to support two different configurations of the workpiece. The jig has a multiplicity of clamps for holding the workpiece, each clamp mounted at the top of a clamp post and each clamp post supported on a pillar mounted on a fixed solid base. The jig is configured by sliding the posts along slides on the pillars to a first position at which the posts can be placed to position the clamps at the correct elevation to support the workpiece at a first configuration position, and inserting a pin through aligned pairs of holes in each of the clamp post and the pillar to prevent the post from sliding from the first position relative to the pillar. The weight of the clamp post and clamp are counterbalanced with a fluid cylinder connected at one end to the clamp post, and connected at the other end to the pillar. To reconfigure the jig, the pin is removed and the clamp post is moved along the pillar to a second position at which the clamps are positioned at the correct elevation to support the workpiece at a second configuration position. The pin is reinserting through a second pair of aligned holes in each pair of clamp post and pillar to prevent the post from sliding from the second position relative to the pillar.
Abstract:
An automatic oil additive injector is disposed over the drain opening in a bottom wall of an engine oil pan and extends into the oil pan. A side port is provided in a housing of the injector for allowing oil to drain therethrough when the oil drain plug is removed. Primary and secondary valve assemblies and a pump operator provided in the housing are activated upon removal of the drain plug to allow a chamber therebetween to fill with a predefined volume of additive, preferably silicone fluid, from a reservoir of the injector and which, upon engagement of the drain plug, dispense the fluid into the oil pan at each oil change to decrease aeration of the oil. In a second embodiment, the additive injector and reservoir are incorporated in the lubricating oil filter header.
Abstract:
A lubricant pump for supplying lubricant to an internal combustion engine, the pump comprising a housing defining a pump chamber, an inlet which is adapted to communicate with a source of lubricant and which communicates with the pump chamber, and an outlet which is adapted to communicate with the internal combustion engine and which communicates with the pump chamber, the housing also at least partially defining a fluid chamber, a source of fluid under pressure, a solenoid for selectively and alternatively affording and preventing communication of the fluid chamber with the fluid source, and a pumping member for drawing lubricant into the pump chamber in response to communication of the fluid chamber with the fluid source and for forcing lubricant out of the pump chamber in the absence of communication between the fluid chamber and the fluid source.
Abstract:
An adaptive lubrication control method used in an adaptive lubrication control system for a machining center having an axial system comprises a controller and a lubricating system. The method uses a built-in macro program unit and programmable logic unit of the controller to acquire the feed rate and load data of the axial system of the machining center for computing the shift parameter of the axial system so that the optimal lubrication timing and lubrication time length can be figured out for controlling the lubricating system to lubricate the axial system automatically.
Abstract:
A metering device for dispensing a predetermined amount of lubricant includes a lubricant reservoir, which retains a lubricant and dispenses it under pressure via an outlet of the lubricant reservoir, and a metering apparatus, which comprises at least one microvalve. The microvalve is fluidly coupled with the outlet of the lubricant reservoir and dispenses the predetermined amount of lubricant in a defined manner. The metering apparatus is spatially separable from the lubricant reservoir.
Abstract:
The invention concerns a transmission oil circuit with an oil pump for feeding oil or another fluid from an oil sump or corresponding fluid sump; with a heat exchanger, the oil flows through, for evacuating the heat from the oil; with a work pressure valve, against which the oil pump conveys the oil, so as to bring the conveyed oil to a preset work pressure for pressure actuation, applying hydraulic pressure or conveying hydraulic pressure to switching valves and/or other transmission components and/or other units outside the transmission, which are arranged in the flow direction upstream of the work pressure valve in a row with respect thereto or in the flow direction downstream of a supply line, which branches off in the transmission oil circuit upstream of the work pressure valve. The invention is characterised in that the heat exchanger can be switched alternately into a first position upstream of the work pressure valve or into a second position downstream of the work pressure valve as regards the circulation sequence of the oil coming out of the oil pump, or the heat exchanger can be switched alternately into a first position upstream of the switching valves or into a second position downstream of the switching valves as regards the circulation sequence of the oil coming out of the oil pump, other transmission components and/or other units in an arrangement inside or downstream of the branched off supply line, upstream or downstream of the branch-off point.
Abstract:
An electromagnetic pump has a solenoid reciprocating a piston that abuts the ball of a first, one-way ball valve coaxially aligned with the piston axis. In the abutting position the piston closes the valve and provides a pump chamber of very small volume. An second, one-way outlet valve is located orthogonal to the first valve to provide a compact structure and further minimize the volume of the pump chamber. A plurality of these inlet valves can be arranged so the pistons are parallel and activated by a single, solenoid activated piston, with the outlet valves being radially orientated to provide a compact structure that simultaneously provides precise fluid amounts to a plurality of locations, such as multiple pistons of a two cycle engine.
