Abstract: A lubricant pump includes a housing mountable to the upper end of a lubricant container and having a vertical central bore, an outlet passage extending between the central bore and an outlet port fluidly connectable with the lubricant distributor and a vent chamber having an inlet and an outlet. A vent inlet passage extends between the central bore and the vent chamber inlet and a vent outlet passage extends between the vent chamber outlet and a vent outlet port fluidly connectable with a container cavity. A movable valve element is disposed within the vent chamber and displaceable along an axis between a position in which the valve element obstructs the chamber inlet and/or the chamber outlet and a second position in which the chamber inlet is fluidly connected with the chamber outlet to provide an internal flow path from the central bore to the vent outlet port.

Abstract: An accumulator includes a tank body having a communication port that communicates the lubricant accommodating space capable of accommodating lubricant with the outside, the tank body extending around an axis, a piston that moves in the axial direction in the tank body to vary the size of the lubricant accommodating space, a spiral spring mechanism having a spiral spring, and a rotational force transmission member that converts a linear movement of the piston into a rotational force around the axis to transmit the converted rotational force. The rotational force transmission member converts a rotational movement due to a restoring force of the spiral spring into a force in the axial direction to move the piston in the axial direction.

Abstract: A variable rate controlled delivery drive mechanism includes a drive mechanism housing, at least partially within which initially resides a biasing member positioned in an initially energized state within an inner cavity of a piston. The drive mechanism may include a gear drive having one or more screws and one or more corresponding nuts. The piston contacts a plunger seal and is configured to axially translate the plunger seal, by force asserted upon it from the biasing member, from a first position to a second position within a drug container for drug delivery. The biasing member is metered from free expansion from its energized state by the gear drive and a gear assembly mechanism having a motor. A drug delivery pump utilizes such variable rate controlled delivery mechanisms. A status reader configured to recognize one or more corresponding status triggers is utilized to provide feedback to a user.

The coiled wave spring is configured to be arranged between a diaphragm damper of the diaphragm damper device and the cover. The coiled wave spring is configured to fix the diaphragm damper to the housing with its elastic force. The coiled wave spring includes a coil portion, a winding initiation portion, and a winding termination portion. The winding initiation portion and the winding termination portion form flat seat windings. The seat windings each have a larger outer diameter than the coil portion. One of the seat windings is configured to be fixed to the diaphragm damper.

Abstract: The present disclosure provides a lubricating system for a dual splined hollow shaft. A fluid dam is formed circumferentially within the hollow shaft to control the lubrication of the dual splines. The fluid dam includes a pair of sidewalls extending radially inward from the inner wall of the hollow shaft to a height defined by a top wait. A channel formed through the pair of sidewalls permits the movement of lubricant between splines of the hollow shaft. An egress port extends from the top wall of the dam through the outer wall of the hollow shaft to permit lubricant to exit the hollow shaft.

Abstract: A wheel hub cover arrangement for covering an outwardly directed wheel hub opening of a wheel hub, which has a cover surface element which is connected to the wheel hub via a wall member and a connection member in such a way that the cover surface element and the wall member enclose a cover volume, wherein at least one venting opening for venting and for pressure-equalizing a vehicle shaft connected to the wheel hub is provided, wherein at least one outlet opening for removing splash water from the cover volume is provided in the wall member, wherein provisions are provided which ensure a fluid connection of the outlet opening with the surroundings of the wall member.

Abstract: A fluid supply device includes a base member including an end plate and a rod perpendicularly extending from a first end of the end plate and defining a first channel axially and a through slot radially, a container attached to a second end of the end plate opposite to the first end and defining a second channel to contain fluid, a pushing member slidably received in the first channel and the second channel, an actuating sleeve threadedly engaging with the rod, and a fixing member attached to the actuating sleeve and extending through the through slot and the pushing member. The actuating sleeve is rotated to drive the pushing member to slide in the first channel and the second channel to push the fluid.

Abstract: A grease gun head has a rotating cylindrical lobed channel situated within the head so that the grease gun may utilize its own grease pump to refill its grease reservoir. The channel and configuration of ports may also be modified to remove the need for rotation of the grease channel.

Abstract: The invention relates to an auxiliary lubrication unit for lubricant introduction devices. The unit comprises a base body (2), in whose longitudinal bore (10) a control piston (6) is displaced axially by a spring (4) towards a seal (9) and also comprises lateral connections (1a, 1p) of a chamber (11) that is delimited by the control piston (6) in the longitudinal bore (10). The connections run from a lubricant pump and to an installation that is to be supplied with lubricant and allowing lubricant to be transported, in the sealing position of the control piston (6), through the chamber (11) from the lubricant pump to the installation. If the pump fails, the control piston (6) can be displaced by remains of auxiliary lubricant from its sealing position, in opposition to the action of the spring (4), into a position in which the connection (1a) to the installation is open and the connection (1p) to the lubricant pump is closed, enabling the installation to the filled with the auxiliary lubricant.

Abstract: A self-contained automatic lubricator for automatically dispensing fluent lubricant over a period of time is provided. The lubricator comprises a cylinder having a front wall with a discharge outlet, a rear wall and cylindrical side walls. A piston is movable within the cylinder from a rear position to a forward position. The piston and the side and front walls of the cylinder define a variable volume chamber for containing the lubricant to be dispensed, and a spring for moving the piston from its rear position towards it front position to reduce the volume of the variable volume chamber over a period of time for expelling lubricant through the discharge outlet. The lubricator further comprises a controller including gearing and an escapement mechanism, for controlling the transfer of energy from the spring to the piston and an electrical element controlling operation of the escapement mechanism (12).

Abstract: A lubricating apparatus comprising a chamber to receive lubricant, an outlet for lubricant, a movable member to drive lubricant from the chamber through the outlet, and a control circuit for periodically activating the motor to dispense lubricant according to a preset schedule. A motor and drive shaft are attached to the movable member through a transmission. Activating the motor in accordance with operator-selected instructions from a pre-programmed micro-processor moves the transmission to drive the movable member towards the outlet to force lubricant therefrom. The apparatus avoids the disadvantage of the prior art which relies on the generation of gas to provide pressure to force lubricant from the apparatus.

Abstract: A new and improved grease shunt valve and lubrication system for a printing press or the like is achieved by the adding of vent drains and/or seals to prevent the accumulation of a waxy-like residue from the grease that interfered with operation of a return spring for closing of the valve. An existing solenoid, operated, grease shunt valve may be retrofitted with an additional body portion having a grease drain vent therein and a seal that seals grease from flowing along a solenoid, actuating rod and into the solenoid core. Preferably, an end plug that seals one end of the return spring is drilled to provide the drain vent for grease flowing into the spring chamber. Vent holes may also be drilled into the solenoid housing to drain and vent grease flowing into the solenoid core.
