Patent number: 8087902Abstract: The invention relates to a hydraulic device with a supply line for pressurized hydraulic fluid and with a lubricating pump that is connected to the supply line in a fluidic fashion. The lubricating pump comprises a hydraulic inlet, a pump element for conveying a lubricant from a reservoir to at least one lubricating point of the hydraulic device, and mechanism for producing a pump stroke of the pump element. The mechanism for producing a pump stroke comprises a base body, a piston unit movable in the base body, and a reversing mechanism for reversing the direction of movement of at least one element of the piston unit.Type: GrantFiled: January 18, 2007Date of Patent: January 3, 2012Assignee: Lincoln GmbHInventors: Zdravko Paluncic, Markus Mandera, Ayzik Grach

Patent number: 8052402Abstract: A hand operated pump for generating negative and positive air pressure. The pump includes a pump body having a pump cylinder and a piston mounted for reciprocation in the cylinder. A selector valve communicates with the cylinder and is moveable between a positive-pressure position and a negative-pressure position. The arrangement is such that operation of an actuator to move the piston through a power stroke when the selector valve is in its negative-pressure position causes the pump to generate negative pressure at an outlet of the pump, and operation of the actuator to move the piston through a power stroke when the selector valve is in its positive-pressure position causes the pump to generate positive pressure at the outlet of the pump. A method of operating such a pump is also disclosed.Type: GrantFiled: October 20, 2008Date of Patent: November 8, 2011Assignee: Lincoln Industrial CorporationInventors: Scott A. Sanders, Ayzik Grach

Publication number: 20060108180Abstract: A device for dispensing a viscous fluid, such as grease gun for dispensing lubricant. The grease gun delivers lubricant with a selectable variation in pressure and/or output. It includes a reservoir, a pump having a reciprocating plunger, an electric motor driving the pump, and a variable speed transmission for transmitting power from the motor to the pump. The transmission has at least two different output speed settings adapted to be selected for reciprocating the plunger at different cyclical frequencies. A cycle indicator provides an indication corresponding to a quantity of lubricant dispensed. Embodiments of the grease gun include a pressure relief valve which inhibits damage due to an over-pressure condition, and a circuit breaker which inhibits damage due to electrical overload.Type: ApplicationFiled: October 7, 2005Publication date: May 25, 2006Applicant: Lincoln Industrial CorporationInventors: Ayzik Grach, Viktor Alekseyev, Christopher Holland, Paul Conley

Patent number: 6405810Abstract: This invention is directed to a method of lubricating an object. The method involves the steps of spraying lubricant on a rotating object, and synchronizing the duration of spray to the rotation of the object so that the spray continues only for an interval of spray time corresponding to rotation of the object through a predetermined range of rotation. Apparatus for spraying lubricant on a rotating object is also disclosed.Type: GrantFiled: November 29, 1999Date of Patent: June 18, 2002Assignee: Lincoln Industrial CorporationInventors: Ayzik Grach, David C.

Patent number: 4976192Abstract: A reciprocating pump comprising a cylinder and a plunger reciprocable in the cylinder, a member at one end of the cylinder having an axial passage in which the plunger is axially slidable, and a seal between the member and the plunger. The pump is characterized in having a sleeve for protecting the seal from the effects of relatively high pressure and pressure fluctuations of fluid in the cylinder. The sleeve surrounds the plunger and is fixed in position inwardly of the member and has an axial bore in line with the axial passage in the member. The sleeve blocks communication from within the cylinder to the axial passage in the member except for such communication as there may be through the bore in the sleeve to the axial passage in the member. The plunger is axially slidable in the bore. The sleeve has internal grooving establishing a pressure reducing path for fluid from the inner to the outer end of the sleeve for reducing the pressure and fluctuations in pressure of fluid from the cylinder on the seal.Type: GrantFiled: January 9, 1989Date of Patent: December 11, 1990Assignee: McNeil (Ohio) CorporationInventor: Ayzik Grach
