    摘要: An impact tool includes a housing having a handle portion defining a first axis, a motor supported by the housing and defining a motor axis, and a rotary impact mechanism arranged on a second axis that is perpendicular to the first axis. The rotary impact mechanism is configured to convert a continuous rotational input from the motor to consecutive rotational impacts upon a workpiece. The rotary impact mechanism includes a chamber containing a hydraulic fluid, an anvil positioned at least partially within the chamber, and a hammer for imparting the consecutive rotational impacts upon the anvil. The hydraulic fluid is configured to attenuate a noise of the rotary impact mechanism that is created by the hammer impacting the anvil. The impact tool further includes a gear train that receives torque from the motor and includes a rotational input that transfers torque to the rotary impact mechanism.

    摘要: A hydraulic hammer assembly is provided. The hydraulic hammer assembly includes a housing and a piston is arranged for reciprocating movement along a longitudinal axis within the housing. A head disposed along the longitudinal axis on an end of the housing and defines a chamber for holding a pressurized gas. The hydraulic hammer assembly further includes a locking mechanism to lock the head on the housing. The locking mechanism includes at least one first flange extending radially from the end of the housing and at least one second flange extending radially from the head, wherein the head is retained on the housing by blocking axial movement of the second flange against the first flange when in a locked position.

    摘要: The present invention relates to a hydraulic breaker. The valve is installed on an inner surface of the cylinder bush and the cylinder inner diameter portion to be movable in the vertical direction. The valve includes an upper valve portion having an upper end surface on which the pressure of the upper cylinder chamber acts, a lower valve portion having a lower end surface on which the pressure of the upper cylinder chamber acts, a first valve expanded-diameter portion which is formed between the upper valve portion and the lower valve portion, of which an outer diameter expands to be greater than outer diameters of the upper valve portion and the lower valve portion, and in which a first upper valve hydraulic pressure area communicates with the first and second flow channels, and a second valve expanded-diameter portion which is formed between the first valve expanded-diameter portion and the lower valve portion, of which an outer diameter expands to be greater than an outer diameter of the first valve expanded-diameter portion, and in which the second upper valve hydraulic pressure area communicates with the fourth flow channel, and the pressure of the valve switching chamber acts on a lower valve hydraulic pressure area having an area greater than an area of the first upper valve hydraulic pressure area.

    摘要: According to the invention, the body of the apparatus includes a flow rate adjustment device including a calibrated opening provided on a high-pressure fluid supply circuit, a bore formed in the body and in which is mounted a slider having a first face located in a first chamber connected to a high-pressure fluid supply circuit upstream from the calibrated opening and a second face located in a second chamber connected to the high-pressure fluid supply circuit downstream from the calibrated opening, the bore receiving the slide including an annular groove connected to a low pressure feedback circuit. The slider is adapted for connecting the annular groove to the first chamber when the pressure difference on either side of the calibrated opening increases beyond a predetermined value in order to divert a portion of the fluid flow supplied by the high-pressure fluid supply circuit to the feedback circuit.
