Patent number: 10518396Abstract: A drive blade lubrication assembly for use in a powered fastener driver (10). The powered fastener driver (10) contains a drive blade (42) which snap-fits with a reciprocating piston (58) by a blade seal (103) assembly. The drive blade lubrication assembly contains a lubricant applying member adapted to apply lubricant to a portion of the drive blade (42); and a lubricant storing device which is in fluid communication with the lubricant applying member. The lubricating storing device is adapted to replenish the lubricant in the lubricant applying member. A powered fastener driver (10) containing a drive blade lubrication assembly is also described. The use of the lubricant storing device in the present invention ensures that lubricant is continuously supplied to the drive blade (42) after long time usage of the powered fastener driver (10), so that friction between the drive blade and the blade seal assembly is minimized.Type: GrantFiled: December 23, 2014Date of Patent: December 31, 2019Assignee: TTI (MACAO COMMERCIAL OFFSHORE) LIMITEDInventors: Xingxing Chen, Jingfeng Zhou, Liguo Ma, Jinlin Zhou

Patent number: 10514029Abstract: An air compressor system operably coupled to a power supply including an air storage tank and an air pump including an air manifold having an inlet configured to receive ambient air. The air pump is fluidly coupled to the air storage tank. The air compressor system also includes a motor having a first current level provided by the power supply to operate the air pump, a valve member in fluid communication with the inlet of the air manifold, and a controller operable to move the valve member to either increase or decrease a rate of ambient air traveling into the manifold. The controller monitors the first current level of the motor to change the rate of ambient air traveling into the manifold.Type: GrantFiled: February 16, 2016Date of Patent: December 24, 2019Assignee: TTI (MACAO COMMERCIAL OFFSHORE) LIMITEDInventor: Joseph Suarez

Patent number: 10512944Abstract: An electric power washer contains a main body having a pump and an electric power source, a hose, a handle, and a control circuit. The hose contains a first end fluidly-connected to the pump and a second end fluidly-connected to the handle, which has a button operatively-connected to the control circuit, which is operatively-connected to the pump and the electric power source. The control circuit controls the pump output and contains a timer. The control circuit permits the pump to normally operate at up to 100% normal power. However, when the button is activated, the control circuit permits the pump to operate at a boost power mode of from about 103% normal power to about 300% normal power. The control circuit intermittently pulses the boost power mode and terminates the boost power mode after a predetermined period of time or when the button is no longer activated, whichever is shorter.Type: GrantFiled: April 8, 2016Date of Patent: December 24, 2019Assignee: TTI (MACAO COMMERCIAL OFFSHORE) LIMITEDInventors: Todd Rickey, Sven Eschrich

Publication number: 20190343347Abstract: Aspects of the present invention relate to a triggerless extractor surface cleaning device for cleaning a surface in which a cleaning solution is distributed to the surface and extracted using suction along with dirt and/or debris on the surface in a continuous operation as the extractor moves along the surface. The extractor further comprises an encoder positioned adjacent a wheel of the extractor for detecting a rotational direction and speed of the wheel to generate a signal. Based on receiving the signal, a controller controls operation of a valve to situationally distribute the cleaning solution to the surface depending on a forward rotation of the wheel and independent of user actuation of a trigger positioned on a handle used to propel the extractor along the surface. Distribution of the cleaning solution can be further optimized based on the detected rotational speed of the wheel.Type: ApplicationFiled: July 25, 2019Publication date: November 14, 2019Applicant: TTI (Macao Commercial Offshore) LimitedInventors: Patrick Diana, Douglas M.
