    Abstract: A hydraulic hammer is disclosed that includes at least one accumulator that is connectable to a hydraulic circuit disposed in the housing of the hammer. The accumulator includes an annular base coupled to a cover with a diaphragm sandwiched therebetween. The annular base includes a proximal end and a distal end. The proximal end of the annular base defines a first central opening. The proximal end of the base in the housing define an annular inlet that encircles the first central opening and that is in communication with the first central opening. The cover also includes a proximal end and a distal end. The proximal end of the cover is coupled to the distal end of the base with the outer periphery of the diaphragm sandwiched therebetween.

    Abstract: A hydro-pneumatic pressure vessel includes a container unit, a connector unit and a protecting unit. The container unit includes an elastic diaphragm dividing an inner space of the container unit into a water chamber and an air chamber. The connector unit includes a water fitting connected to the container unit and formed with a water port. The protecting unit includes a protecting member and a resilient connecting member interconnecting the water fitting and the protecting member. The protecting member is movable from an open position to a blocked position for blocking the water port so as to prevent the diaphragm from being squeezed by an air pressure of the air chamber into the water port.

    Abstract translation: 液压气动压力容器包括容器单元，连接器单元和保护单元。 容器单元包括将容器单元的内部空间分成水室和空气室的弹性隔膜。 连接器单元包括连接到容器单元并形成有水口的水配件。 保护单元包括保护构件和将水配件和保护构件互连的弹性连接构件。 保护构件可以从打开位置移动到阻塞水口的阻挡位置，以防止隔膜被空气室的空气压力挤压到水口中。
