摘要： An actuation device includes a Peltier comprising a first side and a second side; a first module thermally coupled to the first side of the Peltier, and a second module thermally coupled to the second side of the Peltier. The first module is configured to axially contract in response to an increased pressure within the first module and axially expand in response to a decreased pressure within the first module. The second module is configured to axially expand in response to an increased pressure within the second module and axially contract in response to a decreased pressure within the second module.

摘要： A device for cooling and filtering hydraulic fluid comprises a first chamber that includes a fluid inlet connection, a filter cartridge, a bypass manifold, and an inlet to a cooler; and, a second chamber that includes an outlet from the cooler and a fluid outlet connection. The cooler interconnects the first and second chambers through the inlet of the first chamber and the outlet of the second chamber. The bypass manifold is configured to return fluid entering the fluid inlet connection to the fluid outlet connection when a first pressure differential at the bypass manifold is above a first value, and to pass the fluid onto the filter cartridge when the first pressure differential at the bypass manifold is at or below the first value.

摘要： A working machine includes a prime mover, a hydraulic pump driven by power of the prime mover, a cooler including a cooling fan rotated by either the power of the prime mover or hydraulic fluid delivered from the hydraulic pump, and a controller configured or programmed to perform a reduction control for reducing a target fan rotation speed that is a target rotation speed of the cooling fan in response to reduction of an actual prime mover rotation speed that is an actual rotation speed of the prime mover, and to perform, after the reduction control, a restoration control for restoring the target fan rotation speed. The controller is configured or programmed to make a difference between a reduction rate of the target fan rotation speed in the reduction control and an increase rate of the target fan rotation speed in the restoration control.

摘要： An HST circuit has a hydraulic pump that converts a drive force of an engine into energy of oil, and a hydraulic motor that converts the energy of the oil converted by the hydraulic pump into drive energy. Pressure sensors detect a pressure of the oil within the HST circuit. A variable charge pump replenishes the oil into the HST circuit. A controller controls a capacity of the variable charge pump based on the pressure of the oil within the HST circuit detected by the pressure sensors.

摘要： A device for isothermal compression, constant-pressure power generation and physical energy storage includes an air storage tank, a weight, a piston and a piston rod. An inner cavity of the air storage tank is divided into first to third chambers by first and second heat conducting baffles. The piston is arranged in the second chamber. The piston rod has a lower end connected with the piston and an upper end connected with the weight. First and second elastic sealing belts are arranged in the first and third chambers, respectively. The first chamber includes a first water injection port and a first water outlet above the first elastic sealing belt, and the third chamber includes a second water injection port and a second water outlet above the second elastic sealing belt. A bottom of the air storage tank includes an air injection port and a compressed air outlet.

摘要： A hydraulic unit includes an oil tank, a hydraulic pump, a first return pipe, and a first heat exchanger. The oil tank stores a hydraulic oil. The hydraulic pump supplies the hydraulic oil in the oil tank to an actuator. The first return pipe returns the hydraulic oil from a flow path between a discharge port of the hydraulic pump and the actuator to the oil tank. The first heat exchanger causes a coolant to exchange heat with the hydraulic oil returning to the oil tank through the first return pipe.

摘要： One aspect of the invention features a hydraulic fluid cooling and filtering assembly including an inlet tank with an assembly inlet, an outlet with an assembly outlet, and a heat exchanger with multiple fluid channels where channel outlets are spaced apart along a length of the outlet tank over a flow outlet span and cross-flow air channels are formed between the fluid channels. A filter element disposed within the outlet tank includes an internal cavity in communication with the assembly outlet and porous filtering material separating the internal cavity from the heat exchanger channel outlets. The filter element is elongated and has an outer filtering surface extending along at least most of the flow outlet span of the heat exchanger; such that straight lines are defined by the respective inlets and outlets of each fluid channel that intersect the outer filtering surface which is exposed to the fluid channel outlets.
